fixed applying remoteWrite.label for pushed metrics () ()
vmagent: properly add extra labels before sending data to remote storage

labels from `remoteWrite.label` are now added to sent metrics just before they
 are pushed to `remoteWrite.url` after all relabelings, including stream aggregation relabelings ()

lib/promrelabel: add support for a list of series selectors at IfExpression
This makes possible specifying a list of series selectors at the following places:

- Inside `if` option at relabeling rules
- Inside `match` option at stream aggregation rules

lib/streamaggr: follow-up for 736197179e
- Use a byte slice instead of a map for tracking indexes for matching series.
  This improves performance, since access by slice index is faster than access by map key.
- Re-use the byte slice for tracking indexes for matching series.
  This removes unnecessary memory allocations and improves stream aggregation performance a bit.
- Add an ability to return to the previous behvaiour by specifying -remoteWrite.streamAggr.dropInput command-line flag.
  In this case all the input samples are dropped when stream aggregation is enabled.
- Backport the new stream aggregation behaviour from vmagent to single-node VictoriaMetrics when -streamAggr.config
  option is set.
- Improve docs regarding this change at docs/CHANGELOG.md
- Document the new behavior at docs/stream-aggregation.md

lib/streamaggr: follow-up for ff72ca14b9
- Make sure that the last successfully loaded config is used on hot-reload failure
- Properly cleanup resources occupied by already initialized aggregators
  when the current aggregator fails to be initialized
- Expose distinct vmagent_streamaggr_config_reload* metrics per each -remoteWrite.streamAggr.config
  This should simplify monitoring and debugging failed reloads
- Remove race condition at app/vminsert/common.MustStopStreamAggr when calling sa.MustStop() while sa
  could be in use at realoadSaConfig()
- Remove lib/streamaggr.aggregator.hasState global variable, since it may negatively impact scalability
  on system with big number of CPU cores at hasState.Store(true) call inside aggregator.Push().
- Remove fine-grained aggregator reload - reload all the aggregators on config change instead.
  This simplifies the code a bit. The fine-grained aggregator reload may be returned back
  if there will be demand from real users for it.
- Check -relabelConfig and -streamAggr.config files when single-node VictoriaMetrics runs with -dryRun flag
- Return back accidentally removed changelog for v1.87.4 at docs/CHANGELOG.md
