3f85c06b65 app/vmselect/netstorage: reduce CPU contention when upacking time series blocks by unpacking batches of such blocks instead of a single block
This should improve query performance on systems with big number of CPU cores (16 and more)

5e71fab8a6 lib/storage: reduce the maximum number of concurrent merge workers to GOMAXPROCS/2
Previously the limit has been raised to GOMAXPROCS, but it has been appeared that this
increases query latencies since more CPUs are busy with merges.

While at it, substitute `*MergeConcurrencyLimitCh` channels with simple integer limits.

e7959094f6 lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected
The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts.

Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon,
which should return CPU and disk IO usage to normal levels.

922d9aadf2 lib/storage: properly update vm_slow_row_inserts_total metric when importing multiple data points per time series at once
Previously the `vm_slow_row_inserts_total` metric may be incremented multiple times for different data points per a single time series,
while only a single increment is needed when inserting the first data point for this time series.
