49bf3abf67 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

2ac5f00d98 app/vmselect: propagate errors from vmstorage to response to the client if -search.denyPartialResponse command-line flag is set 
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/891

This commit also adds `"isPartial":{true|false}` field to `/api/v1/*` responses. `"isPartial":true` is set when the response
is based on a partial data because some of vmstorage nodes weren't available during query processing.
