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:

    rate(process_cpu_seconds_total[5m]) / process_cpu_cores_available > 0.9

app/vmselect/promql: optimize queries, which join on _info metrics. 
Automatically add common filters from one side of binary operation
to the other side before sending the query to storage subsystem.

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.

app/vmselect/promql: add support for @ modifier 
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]`

lib/storage: convert alternate regexps into Graphite wildcards inside __graphite__ pseudo-label 
For example, `{__graphite__=~"foo.(bar|baz)"}` is automatically converted to `{__graphite__=~"foo.{bar,baz}"}` before execution.
This allows using multi-value Grafana template variables such as `{__graphite__=~"foo.($app)"}`.

It is expected that the de-duplication is applied during importing the exported data.

The deduplication is applied only when exporting data via /api/v1/export if `reduce_mem_usage=1` query arg isn't passed to the request.

lib/promscrape: reduce memory usage if -promscrape.noStaleMarkers command-line flag is passed 
Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled.
This should reduce memory usage when the scraped targets return large responses.

lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice 
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

8a6a36429a app/vminsert/netstorage: disable rerouting by default 
Production clusters work more stable with the disabled rerouting during rolling restarts and/or
during spikes in time series churn rate. So it would be better disabling the rerouting by default.

The re-routing can be enabled by passing `-disableRerouting=false` command-line flag to `vminsert` nodes.

f3e89754a9 lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric 
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

d6bd956930 lib/promrelabel: add keep_metrics and drop_metrics actions to relabeling rules 
These actions simlify metrics filtering. For example,

- action: keep_metrics
  regex: 'foo|bar|baz'

would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted.

The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above:

- action: keep_metrics
  regex:
  - foo
  - bar
  - baz
