app/vmselect: follow-up for 626073bca8
...
* Rename -search.maxMetricsPointSearch to -search.maxSamplesPerQuery, so it is more consistent with the existing -search.maxSamplesPerSeries
* Move the -search.maxSamplesPerQuery from vmstorage to vmselect, so it could effectively limit the number of raw samples obtained from all the vmstorage nodes
* Document the -search.maxSamplesPerQuery in docs/CHANGELOG.md

lib/workingsetcache: properly switch to whole
mode
...
Previously the switch from `split` to `whole` mode had been performed too early,
e.g. when the current cache size became bigger than 1/4 of the allowed cache size.
Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.
This change can reduce memory usage for data ingestion path when big number of active time series are ingested.
