vmalert: support /rules path for Grafana's ngalert requests (#2593) 
Unexpectedly, Grafana makes an extra request to `/rules`
handler in addition to `/api/v1/rules` calls in alerts UI.
This happens only for Grafana versions older than 8.5.*.
Apparently, this is related to support of other monitoring
systems.
Prometheus responds with `text/html` content for UI page `/rules`
to such requests. Actually, returning just a blank page with
SC=200 works as well.

Returning actual response of `/api/v1/rules`
results in error in Grafana since it expects a `yaml` (?) in response.
So we add a placeholder to `vmalert`.

docs: fix liquid syntax errors (#2592) 
For liquid text processor double braces `{{` `}}`
are special chars for templating.
Since we use them in some of our docs with different purpose,
we must escape them to avoid syntax errors from liquid.

For escaping curly braces we use bult-in plugin which helps
to enclose sections of text via `{% raw %}` and `{% endraw %}`.
This approach prevents liquid syntax errors and makes render correct.

Update docs (#2566) 
* deployment/docker: pass `-buildvs=false` to `go build` for production builds

This should resolve the `error obtaining VCS status: exit status 128` error
when the environment contains incorrect version of git or has incorrect access rights
to the directory with VictoriaMetrics source code.

See the following links for additional info:
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2508#issuecomment-1117126702 ,
- https://github.com/google/ko/issues/672
- https://github.com/golang/go/issues/49004

* lib/netutil: limit the number of concurrently established connections when calling ConnPool.Get()

This should reduce potential spikes in the number of established connections in the following cases:
- when the connection establishing procedure becomes temporarily slow
- after a temporary spike in the rate of ConnPool.Get() calls

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2552

* docs/CHANGELOG.md: document c8af625bcc

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1322#issuecomment-1120276146

Export "null" in jsonl instead of NaN (#2518) 
* Export "null" in jsonl instead of NaN

The NaN appeared because of staleness markers that were added for compatibility. I think it's better to use json `null`, implemented here.

Also maybe it also makes sense to add a flag like `?skip-staleness-markers=true` to `/export`, to skip nulls at all?

app/vmselect/promql: fix duplicate time series error on joins against time series filtered by values 
This should prevent from `duplicate time series` errors when executing the following query:

kube_pod_container_resource_requests{resource="cpu"} * on (namespace,pod) group_left() (kube_pod_status_phase{phase=~"Pending|Running"}==1)

where `kube_pod_status_phase{phase=~"Pending|Running"}==1` filters out diplicate time series

lib/promscrape: optimize getScrapeWork() function 
Reduce the number of memory allocations in this function. This improves its performance by up to 50%.
This should improve service discovery speed when big number of potential targets with big number of meta-labels
are generated by service discovery.
