* deployment: create a separate env for VictoriaLogs
The new environment consists of the following components:
* VictoriaLogs
* fluentbit for collecting logs and sending to VictoriaLogs
* VictoriaMetrics for scraping and storing metrics from fluentbit and VictoriaLogs
* Grafana with VictoriaLogs datasource for monitoring
-----------------
The motivation for creating a separate environment is to simplify existing environments
and make it easier to update or modify them in future.

Currently the docker-compose examples for loading `victoriametrics-datasource` uses 2 environment variables:
- `GF_ALLOW_LOADING_UNSIGNED_PLUGINS`
- `GF_DEFAULT_APP_MODE`
I believe both of the env vars are trying to achieve the same thing. `GF_DEFAULT_APP_MODE` disables code signing for all plugins and `GF_ALLOW_LOADING_UNSIGNED_PLUGINS` intends to disable code signing for just `victoriametrics-datasource`.
Keeping the scope narrowed to just `victoriametrics-datasource` would be preferable in this case.
Unfortunately `GF_ALLOW_LOADING_UNSIGNED_PLUGINS` is misspelled. According to [grafana docs](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#override-configuration-with-environment-variables), the format is supposed to be `GF_<SectionName>_<KeyName>`. In other words the current env var is missing the section name.
This PR proposes to:
1. fix the typo
2. remove the global disablement of code signing
Alternatively, if you prefer to keep codesigning disabled globally, please remove `GF_ALLOW_LOADING_UNSIGNED_PLUGINS` env var as it confuses things

* - apply v1.10 changes
- chapter on model types (uni/multivariate and rolling)
* - update self-monitoring labels description
- fix typos
* fix duplicated text and link rendering

During background downsampling, rate(vm_deduplicated_samples_total{type="merge"}) could be much bigger than
rate(vm_rows_added_to_storage_total) and it could last quite some time,
which causes negative values of Storage full ETA and confuses users, see playground.
Instead of trying to get more accurate results during downsampling, I think it's ok to ignore
vm_deduplicated_samples_total at all, it's more reasonable to see Storage full ETA increase after downsampling.

Each Grafana dashboard has unique ID which can be used to fetch the dashboard
from grafana.com: https://grafana.com/grafana/dashboards/11176
The same dashboard can be accessed via URL with slug: https://grafana.com/grafana/dashboards/11176-victoriametrics-cluster/
But using slug implies that any change to dashboard name will break the link.
So it is better to just use ID, so the dashboard URL will never break.

It updates some of the alerting rules to remove unnecessary aggregations.
It keeps aggregations for expressions which are using multiple time series

Aggregations with by() have one sideeffect, that any custom labels you add to hosts are dropped too which can be used for alerts routing.
Therefore, some good practice could be to use without() instead, with labels, like without(path) , or without(url) to get same aggregations but with any external labels left intact.

Using `min_over_time` should reduce the amount of false positives when
component is running in near-the-threshold state. Now it should trigger
only if all collected samples were above the threshold on 10m interval.

* lib/promscrape: add metric `vm_promscrape_scrapes_skipped_total`
add metric `vm_promscrape_scrapes_skipped_total`to show whether vmagent skips the scrapes.
This could happen if vmagent is overloaded or target is responding too slow for configured `scrape_interval`.
The follow-up commit should add a corresponding alerting rule and panel to vmagent dashboard.

The `ConcurrentFlushesHitTheLimit` could be related to components like
vminsert, vmstorage, vm-single-node and vmagent. Moving this alert
to the `health` section of alerts will be benefitial for all components
and will remove the duplicates from single/cluster alerts.

- Parse protobuf if Content-Type isn't set to `application/json` - this behavior is documented at https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki
- Properly handle gzip'ped JSON requests. The `gzip` header must be read from `Content-Encoding` instead of `Content-Type` header
- Properly flush all the parsed logs with the explicit call to vlstorage.MustAddRows() at the end of query handler
- Check JSON field types more strictly.
- Allow parsing Loki timestamp as floating-point number. Such a timestamp can be generated by some clients,
which store timestamps in float64 instead of int64.
- Optimize parsing of Loki labels in Prometheus text exposition format.
- Simplify tests.
- Remove lib/slicesutil, since there are no more users for it.
- Update docs with missing info and fix various typos. For example, it should be enough to have `instance` and `job` labels
as stream fields in most Loki setups.
- Allow empty of missing timestamps in the ingested logs.
The current timestamp at VictoriaLogs side is then used for the ingested logs.
This simplifies debugging and testing of the provided HTTP-based data ingestion APIs.
The remaining MAJOR issue, which needs to be addressed: victoria-logs binary size increased from 13MB to 22MB
after adding support for Loki data ingestion protocol at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4482 .
This is because of shitty protobuf dependencies. They must be replaced with another protobuf implementation
similar to the one used at lib/prompb or lib/prompbmarshal .
