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/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.

lib/promscrape: add -promscrape.minResponseSizeForStreamParse command-line option for automatic switching to stream parsing mode when scraping targets with big responses
This should reduce memory usage when vmagent scrapes targets with non-uniform response sizes.
This is common case in Kubernetes monitoring.

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.

- action: keep_metrics
  regex:
  - foo
  - bar

d5622b32e2 lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets
Store the scraped response body instead of storing the parsed and relabeld metrics.
This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics.
This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

This should also reduce CPU usage, since the marshaling of the parsed
and relabeld metrics has been substituted by response body copying.

cdc372bb98 app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries
This option allows reducing CPU usage a bit when VictoriaMetrics is used
for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.

226143f31b lib/promscrape: add ability to disable sending Prometheus staleness markers with -promscrape.disableStaleMarkers command-line flag
This option can be useful when vmagent consumes too much additional memory
for staleness markers functionality and when staleness markers aren't needed.
