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.

vmalert: set alert's source link to UI instead of JSON source (#2986) 
We switch default alert's source link to redirect user
to vmalert's UI instead of previous JSON object. While it breaks
compatibility, it also supposed to improve user's experience.
The old behavior can be achieved by updating `-external.alert.source`
command-line flag.

lib/promscrape: automatically generate additional per-target labels for targets with non-zero series limit 
The following metrics are generated:

- scrape_series_limit
- scrape_series_current
- scrape_series_limit_samples_dropped

These metrics simplify alerting on targets, which expose too many time series

See https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics
and https://docs.victoriametrics.com/vmagent.html#cardinality-limiter for more details

lib/promscrape: retry http requests if the server returns 429 status code

app/vmselect/netstorage: improve scalability of blocks processing on systems with multiple CPU cores 
Previously a single syncwg.WaitGroup was used for tracking the lifetime of processBlock callbacks
across all the per-vmstorage goroutines. This could be slow on systems with many CPU cores
because of inter-CPU synchronization overhead.

Use a separate per-vmstorage sync.WaitGroup instead in order to reduce inter-CPU synchronization overhead.
This should imrpove performance for heavy queries over big number of blocks on multi-CPU systems.

Returning nil error when storage is in RO mode results

lib/storage: return marshaled metric names from SearchMetricNames 
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.

While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.

Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series

all: limit the maximum memory usage for regexp cache, which stores parsed regular expressions in MetricsQL queries 
Previously the cache could store 10K unique regexps. When every regexp is huge (e.g. hundreds of kilobytes),
then the total cache size could grow to multiples of gigabytes. Now the cache size is limited by the total length
of all cached regexps. So huge regexps won't result in high memory usage for the cache.

e40d015e9a vmselect: make vm_partial_results_total consistent 
Metrics `vm_partial_results_total` and `vm_requests_total` serving
the similar purpose, but contain inconsistent set of labels.
This change updates `vm_partial_results_total` labels to be consistent
with `vm_requests_total`.

The change breaks backward compatibility with assumption that
`vm_partial_results_total` wasn't widely used, since it is
not documented and absent in the alerts and dashboards.
