lib/promscrape/discovery/hetzner: follow-up after 03a97dc678 
- docs/sd_configs.md: moved hetzner_sd_configs docs to the correct place according to alphabetical order of SD names,
  document missing __meta_hetzner_role label.
- lib/promscrape/config.go: added missing MustStop() call for Hetzner SD,
  and moved the code to the correct place according to alphabetical order of SD names.
- lib/promscrape/discovery/hetzner: properly handle pagination for hloud API responses,
  populate missing __meta_hetzner_role label like Prometheus does.
- Properly populate __meta_hetzner_public_ipv6_network label like Prometheus does.
- Remove unused SDConfig.Token.
- Remove "omitempty" annotation from SDConfig.Role field, since this field is mandatory.

```
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to `<service_or_node_addr>:<service_port>`, where `<service_or_node_addr>` is the service address. If the service address is empty,
then the node address is used instead. The `<service_port>` is the service port.
The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):
* `__meta_consul_address`: the address of the target

The list of discovered Consul targets is refreshed at the interval, which can be configured via `-promscrape.consulSDCheckInterval` command-line flag.
If you have performance issues with `consul_sd_configs` on a large cluster, then consider using [consulagent_sd_configs](#consulagent_sd_configs) instead.
## consulagent_sd_configs
Consul Agent SD configuration allows retrieving scrape targets from [Consul Agent API](https://developer.hashicorp.com/consul/api-docs/agent/service).
When using the Agent API, only services registered in the locally running Consul Agent are discovered.
It is suitable for huge clusters for which using the [Catalog API](https://developer.hashicorp.com/consul/api-docs/catalog#list-services) would be too slow or resource intensive,
in other cases it is recommended to use [consul_sd_configs](#consul_sd_configs).
Configuration example:
```yaml
scrape_configs:
- job_name: consulagent
consulagent_sd_configs:
# server is an optional Consul Agent to connect to. By default, localhost:8500 is used
- server: "localhost:8500"
# token is an optional Consul API token.
# If the token isn't specified, then it is read from a file pointed by CONSUL_HTTP_TOKEN_FILE
# environment var or from the CONSUL_HTTP_TOKEN environment var.
# token: "..."
# datacenter is an optional Consul API datacenter.
# If the datacenter isn't specified, then it is read from Consul server.
# See https://www.consul.io/api-docs/agent#read-configuration
# datacenter: "..."
# namespace is an optional Consul namespace.
# See https://developer.hashicorp.com/consul/docs/enterprise/namespaces
# If the namespace isn't specified, then it is read from CONSUL_NAMESPACE environment var.
# namespace: "..."
# scheme is an optional scheme (http or https) to use for connecting to Consul server.
# By default, http scheme is used.
# scheme: "..."
# services is an optional list of services for which targets are retrieved.
# If omitted, all services are scraped.
# See https://www.consul.io/api-docs/catalog#list-nodes-for-service .
# services: ["...", "..."]
# tag_separator is an optional string by which Consul tags are joined into the __meta_consul_tags label.
# By default, "," is used as a tag separator.
# Individual tags are also available via __meta_consul_tag_<tagname> labels - see below.
# tag_separator: "..."
# filter is optional filter for service nodes discovery request.
# Replaces tags and node_metadata options.
# consul supports it since 1.14 version
# list of supported filters https://developer.hashicorp.com/consul/api-docs/catalog#filtering-1

These specified names are periodically queried to discover a list of targets with the interval
configured via `-promscrape.dnsSDCheckInterval` command-line flag.
Configuration example:
```yaml
scrape_configs:
- job_name: dns
dns_sd_configs:
# names must contain a list of DNS names to query.
- names: ["...", "..."]
# type is an optional type of DNS query to perform.
# Supported values are: SRV, A, AAAA or MX.
# By default, SRV is used.
# type: ...
# port is a port number to use if the query type is not SRV.
# port: ...
```
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to the `<addr>:<port>`, where `<addr>` is the discovered DNS address, while `<port>` is either the discovered port for SRV records or the port

The `services` role discovers all Swarm services.
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to `<ip>:<port>`, where `<ip>` is the endpoint's virtual IP, while the `<port>` is the published port of the service.
If the service has multiple published ports, then multiple targets are generated - one per each port.
If the service has no published ports, then the `<port>` is set to the `port` value obtained from `dockerswarm_sd_configs`.
Available meta labels for `role: services` during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):

* `__meta_dockerswarm_network_label_<labelname>`: each label of the network
* `__meta_dockerswarm_network_scope`: the scope of the network
* `role: tasks`
The `tasks` role discovers all Swarm tasks.
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to `<ip>:<port>`, where the `<ip>` is the node IP, while the `<port>` is the published port of the task.
If the task has multiple published ports, then multiple targets are generated - one per each port.
If the task has no published ports, then the `<port>` is set to the `port` value obtained from `dockerswarm_sd_configs`.
Available meta labels for `role: tasks` during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):

The `role: node` discovers one target per cluster node.
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to `<ip>:<port>`, where `<ip>` is to the first existing address of the Kubernetes node object in the address type order
of `NodeInternalIP`, `NodeExternalIP`, `NodeLegacyHostIP` and `NodeHostName`,
while `<port>` is the kubelet port on the given node.
Available meta labels for `role: node` during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):

Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to `<service_name>.<namespace>:<port>`, where `<service_name>` is the service name, `<namespace>` is the service namespace
and `<port>` is the service port.
If the service has multiple ports, then multiple targets are discovered for the service - one per each port.
This is generally useful for blackbox monitoring of a service. The target address will be set to the Kubernetes DNS name
of the service and respective service port.

to `<ip>:<port>`, where `<ip>` is pod IP, while `<port>` is the exposed container port.
If the pod has multiple container ports, then multiple targets are generated for the pod - one per each exposed container port.
If the pod has no exposed container ports, then the `__address__` for pod target is set to the pod IP.
Available meta labels for `role: pod` during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):

* `__meta_kubernetes_endpoint_address_target_kind`: Kind of the endpoint address target.
* `__meta_kubernetes_endpoint_address_target_name`: Name of the endpoint address target.
If the endpoints belong to a service, all labels of the `role: service` are attached.
For all targets backed by a pod, all labels of the `role: pod` are attached.
* `role: endpointslice`
The `role: endpointslice` discovers targets from existing endpointslices.
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to `<addr>:<port>`, where `<addr>` is the endpoint address, while `<port>` is the endpoint port.
If the endpoint has multiple ports, then a single target per each port is generated.
If the endpoint is backed by a pod, all additional container ports of the pod, not bound to an endpoint port, are discovered as targets as well.
Available meta labels for `role: endpointslice` during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):
* `__meta_kubernetes_namespace`: The namespace of the endpoints object.
* `__meta_kubernetes_endpointslice_name`: The name of endpointslice object.
For all targets discovered directly from the endpointslice list (those not additionally inferred from underlying pods), the following labels are attached:
* `__meta_kubernetes_endpointslice_address_target_kind`: Kind of the referenced object.
* `__meta_kubernetes_endpointslice_address_target_name`: Name of referenced object.
* `__meta_kubernetes_endpointslice_address_type`: The ip protocol family of the address of the target.
* `__meta_kubernetes_endpointslice_endpoint_conditions_ready`: Set to true or false for the referenced endpoint's ready state.
* `__meta_kubernetes_endpointslice_endpoint_topology_kubernetes_io_hostname`: Name of the node hosting the referenced endpoint.
* `__meta_kubernetes_endpointslice_endpoint_topology_present_kubernetes_io_hostname`: Flag that shows if the referenced object has a kubernetes.io/hostname annotation.

* `__meta_kubernetes_endpointslice_port_name`: Named port of the referenced endpoint.
* `__meta_kubernetes_endpointslice_port_protocol`: Protocol of the referenced endpoint.
If the endpoints belong to a service, all labels of the `role: service` are attached.
For all targets backed by a pod, all labels of the `role: pod` are attached.
* `role: ingress`
The `role: ingress` discovers a target for each path of each ingress.
Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
to the host obtained from ingress spec.
If the ingress has multiple specs with multiple hosts, then a target per each host is created.
This is generally useful for blackbox monitoring of an ingress.
Available meta labels for `role: ingress` during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):
* `__meta_kubernetes_namespace`: The namespace of the ingress object.
