a1911e1330 app/vmselect/netstorage: unpack time series data in mostly local big chunks 
This should improve performance on multi-CPU systems for queries selecting time series with big number of raw samples

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

f765985947 lib/fs: replace fs.OpenReaderAt with fs.MustOpenReaderAt 
All the callers for fs.OpenReaderAt expect that the file will be opened.
So it is better to log fatal error inside fs.MustOpenReaderAt instead of leaving this to the caller.

82973f8ae7 Revert "lib/storage: remove unused fetchData arg from BlockRef.MustReadBlock" 
This reverts commit bab6a15ae0.

Reason for revert: the `fetchData` arg is used in cluster branch.
Leaving this arg in master branch makes smaller the diff with cluster branch.
