8ee8660ac4 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

ca75432e66 app/vmselect: do not track queries with less than 1ms execution time at /api/v1/status/top_queries

4ba3fd9e6d lib/workingsetcache: switch from split cache to full cache after the cache size exceeds 95% of split capacity 
Previously the switch occurred when the cache size becomes 100% of its capacity. The cache size could never reach 100% capacity.
This could prevent from switching from the split cache to full cache, thus reducing the cache effectiveness.
