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.

app/vmselect/netstorage: increase concurrency when processing small number of time series with big number of data points per each time series
...
Previously VictoriaMetrics was processing up to 32 time series in a single goroutine.
This could be slow if each time series contains big number of data points (10M+ or more), since only a single CPU core could be loaded with work,
while other CPU cores were idle. Fix this by launching GOMAXPROCS workers for time series processing.
This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/572
