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
The 429 status code means that the server is overwhelmed with requests.
The client can retry the request after some wait time.
Implement this strategy for service discovery and scrape requests.

app/vmselect: follow-up after 63e0f16062
* Explicitly store a pointer to UserReadableError in the error interface.
  Previously Go automatically converted the value to a pointer before storing in the error interface.

* Add Unwrap() method to UserReadableError, so it can be used transparently with the other code,
  which calls errors.Is() and errors.As().

* Document the change in docs/CHANGELOG.md

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.

lib/storage: prevent excessive loops when storage is in RO (#2962)
* lib/storage: prevent excessive loops when storage is in RO

Returning nil error when storage is in RO mode results
into excessive loops and function calls which could
result into CPU exhaustion. Returning an err instead
will trigger delays in the for loop and save some resources.

Since the minimum supported Go version for VictoriaMetrics is Go1.17,
then the `-mod=vendor` option is no longer needed.
