vmselect/promql: add alphanumeric sort by label (sort_by_label_numeric) (#2982)
* vmselect/promql: add alphanumeric sort by label (sort_by_label_numeric)

* vmselect/promql: fix tests, add documentation

* vmselect/promql: update test

* vmselect/promql: update for alphanumeric sorting, fix tests

* vmselect/promql: remove comments

* vmselect/promql: cleanup

* vmselect/promql: avoid memory allocations, update functions descriptions

* vmselect/promql: make linter happy (remove ineffectual assigment)

* vmselect/promql: add test case, fix behavior when strings are equal

* vendor: update github.com/VictoriaMetrics/metricsql from v0.44.1 to v0.45.0

this adds support for sort_by_label_numeric and sort_by_label_numeric_desc functions

* wip

* lib/promscrape: read response body into memory in stream parsing mode before parsing it

This reduces scrape duration for targets returning big responses.

The response body was already read into memory in stream parsing mode before this change,
so this commit shouldn't increase memory usage.

* wip

app/vmalert: follow-up after 8441375da2
- Rename logDebug() to logDebugf() and pass format string together
  with format args directly to logDebugf(). This eliminates fmt.Sprintf()
  overhead at logDebug() call site when debugging is disabled.

- Format labels in debug message in Prometheus format, e.g. {label1="value1",...labelN="valueN"}

vmalert: add debug mode for alerting rules (#3055)
* vmalert: add `debug` mode for alerting rules

Debug information includes alerts state changes and requests
sent to the datasource. Debug can be enabled only on rule's
level. It might be useful for debugging unexpected
behaviour of alerting rule.

docs/Release-Guide.md: require manual push of the created release tags to public Github
The automated push of release tags to Github require specifying the remote repository name
when doing `git push <remote-repo-name> v1.xx.y`.
The remote repository name can differ in different environments,
so it cannot be put into Makefile rule.

TODO: create a Makefile rule, which generates standard remote names for public
and private repositories in Git, so `git push` for release tags could be automated then.

lib/storage: verify that timestamps in block are in the range specified by blockHeader.{Min,Max}Timestamp when upacking the block
This should reduce chances of unnoticed on-disk data corruption.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2998
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3011

This change modifies the format for data exported via /api/v1/export/native -
now this data contains MaxTimestamp and PrecisionBits fields from blockHeader.

This is OK, since the native export format is undocumented.
