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

* docs/Cluster-VictoriaMetrics.md: typo fix: `by by` -> `by`

* docs: add `resource usage limits` docs, which describe fine-grained tuning for various resource usage limits

* docs/Cluster-VictoriaMetrics.md: the `/api/v1/label/.../values` query can take CPU and ram at both vmstorage and vmselect

* Update root Readme and root vmagent readme

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?

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

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.

* lib/discovery/consul: update services on the watcher's start

Previously, watcher's start was only initing goroutines for discovery
but not waiting for the first iteration to end. It means first Consul
discovery wasn't returning discovered targets until the next iteration.

The change makes the watcher's start blocking until we get first discovery
iteration done and all registries updated.

lib/index: reduce read/write load after indexDB rotation (#2177) 
* lib/index: reduce read/write load after indexDB rotation

IndexDB in VM is responsible for storing TSID - ID's used for identifying
time series. The index is stored on disk and used by both ingestion and read path.

IndexDB is stored separately to data parts and is global for all stored data.
It can't be deleted partially as VM deletes data parts. Instead, indexDB is
rotated once in `retention` interval.

The rotation procedure means that `current` indexDB becomes `previous`,
and new freshly created indexDB struct becomes `current`. So in any time,
VM holds indexDB for current and previous retention periods.
When time series is ingested or queried, VM checks if its TSID is present
in `current` indexDB. If it is missing, it checks the `previous` indexDB.
If TSID was found, it gets copied to the `current` indexDB. In this way
`current` indexDB stores only series which were active during the retention
period.

To improve indexDB lookups, VM uses a cache layer called `tsidCache`. Both
write and read path consult `tsidCache` and on miss the relad lookup happens.

When rotation happens, VM resets the `tsidCache`. This is needed for ingestion
path to trigger `current` indexDB re-population. Since index re-population
requires additional resources, every index rotation event may cause some extra
load on CPU and disk. While it may be unnoticeable for most of the cases,
for systems with very high number of unique series each rotation may lead
to performance degradation for some period of time.

This PR makes an attempt to smooth out resource usage after the rotation.
The changes are following:
1. `tsidCache` is no longer reset after the rotation;
2. Instead, each entry in `tsidCache` gains a notion of indexDB to which
they belong;
3. On ingestion path after the rotation we check if requested TSID was
found in `tsidCache`. Then we have 3 branches:
3.1 Fast path. It was found, and belongs to the `current` indexDB. Return TSID.
3.2 Slow path. It wasn't found, so we generate it from scratch,
add to `current` indexDB, add it to `tsidCache`.
3.3 Smooth path. It was found but does not belong to the `current` indexDB.
In this case, we add it to the `current` indexDB with some probability.
The probability is based on time passed since the last rotation with some threshold.
The more time has passed since rotation the higher is chance to re-populate `current` indexDB.
The default re-population interval in this PR is set to `1h`, during which entries from
`previous` index supposed to slowly re-populate `current` index.

The new metric `vm_timeseries_repopulated_total` was added to identify how many TSIDs
were moved from `previous` indexDB to the `current` indexDB. This metric supposed to
grow only during the first `1h` after the last rotation.

lib/cgroup: expose process_cpu_cores_available metric 
This metric shows the number of CPU cores available to the process.
This allows creating alerting rules on CPU saturation with the following query:

vendor: update github.com/VictoriaMetrics/metricsql from v0.37.0 to v0.38.0 
This adds more optimization cases for https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization

For example:

* Multi-level transform functions. For example, abs(round(foo{a="b"})) + bar{x="y"}
  is now optimized to abs(round(foo{a="b",x="y"})) + bar{a="b",x="y"}
* Binary operations with `on()`, `without()`, `group_left()` and `group_right()` modifiers.
  For example, foo{a="b"} on (a) + bar is now optimized to foo{a="b"} on (a) + bar{a="b"}
* Multi-level binary operations. For example, foo{a="b"} + bar{x="y"} + baz{z="q"}
  is now optimized to foo{a="b",x="y",z="q"} + bar{a="b",x="y",z="q"} + baz{a="b",x="y",z="q"}
* Aggregate functions. For example, sum(foo{a="b"}) by (c) + bar{c="d"}
  is now optimized to sum(foo{a="b",c="d"}) by (c) + bar{c="d"}

lib/{mergeset,storage}: properly limit cache sizes for indexdb 
Previously these caches could exceed limits set via `-memory.allowedPercent` and/or `-memory.allowedBytes`,
since limits were set independently per each data part. If the number of data parts was big, then limits could be exceeded,
which could result to out of memory errors.

Add support for `@` modifier in MetricsQL according to https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier

Extend the support with the following features:
* Allow using `@` modifier everywhere in the query. For example, `sum(foo) @ end()`
* Allow using arbitrary expression as `@` modifier. For example, `foo @ (end() - 1h)`
  returns `foo` value at `end - 1 hour` timestamp on the selected time range `[start ... end]`
