previously, if native block cannot be unmarshaled, wg.Done wasn't called by unmarshal work.
It leads to connection blocking and possible dead-lock at client side
Before, relabeling for notifier configured via file was supported
only for target labels discovered via SD.
With this change, new config field `alert_relabel_configs` is introduced
for applying relabeling to labels of sent alerts.

This metric is equivalent to `vm_available_memory_bytes`, but it has better name,
since the metric is related to a process, not VictoriaMetrics itself.
Leave `vm_available_memory_bytes` for backwards compatibility.
To improve compatibility with Prometheus alerting the order of
templates processing has changed.
Before, vmalert did all labels processing beforehand. It meant
all extra labels (such as `alertname`, `alertgroup` or rule labels)
were available in templating. All collisions were resolved in favour
of extra labels.
In Prometheus, only labels from the received metric are available in
templating, so no collisions are possible.
This change makes vmalert's behaviour similar to Prometheus.
For example, consider alerting rule which is triggered by time series
with `alertname` label. In vmalert, this label would be overriden
by alerting rule's name everywhere: for alert labels, for annotations, etc.
In Prometheus, it would be overriden for alert's labels only, but in annotations
the original label value would be available.

This should improve the performance for items sorting inside inmemoryBlock.MarshalUnsortedData
if they have common prefix.
While at it, improve the performance for inmemoryBlock.updateCommonPrefix for sorted items.
This should improve performance for inmemoryBlock.MarshalSortedData during background merge.
This reduces memory usage under production workloads by up to 10%,
while CPU spent on GC remains roughly the same.
The CPU spent on GC can be monitored with go_memstats_gc_cpu_fraction metric
The following actions are taken:
- Increase the TLS hashdshake timeout from 5 seconds to 10 seconds
- Increase dial timeout from 5 seconds to 30 seconds
- Specify DialContext instead of Dial in http.Transport. This allows properly handling
the Context arg during dialing the remote storage
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1699
* lib/protoparser: changes ParseStream for native format
uses reader instead of http.Request
updates app/vmagent and app/vmagent method usage
* app/vmctl: add verify-block subcommand
it allows to check exported from VictoriaMetrics data block in native format
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2362
Update app/vmctl/README.md

The new flag `datasource.disableKeepAlive` allows disabling keepalive
connections. This may be useful if there are multiple datasource
replicas (e.g. vmselects) behind the HTTP balancer to avoid uneven
load spread because of long-lived connections.
