6865f3b497 Revert "lib/mergeset: remove a pool for inmemoryBlock structs" 
This reverts commit 793fe39921.

Reason to revert: production testing revealed possible slowdown when registering big number of new time series

7b33bc67a1 lib/mergeset: remove a pool for inmemoryBlock structs 
The pool for inmemoryBlock struct doesn't give any performance gains in production workloads,
while it may result in excess memory usage for inmemoryBlock structs inside the pool during
background merge of indexdb.

e183a5c532 vmalert: automatically reload configuration on file change (#1326) 
New flag `-rule.configCheckInterval` defines how often `vmalert` will re-read
config file. If it detects any changes, the config will be reloaded.
This behaviour is turned off by default.

6b90570ed3 lib/uint64set: store pointers to bucket16 instead of bucket16 objects in bucket32 
This speeds up bucket32.addBucketAtPos() when bucket32.buckets contains big number of items,
since the copying of bucket16 pointers is much faster than the copying of bucket16 objects.

This is a cpu profile for copying bucket16 objects:

      10ms     13.43s (flat, cum) 32.01% of Total
      10ms      120ms    650:	b.b16his = append(b.b16his[:pos+1], b.b16his[pos:]...)
         .          .    651:	b.b16his[pos] = hi
         .     13.31s    652:	b.buckets = append(b.buckets[:pos+1], b.buckets[pos:]...)
         .          .    653:	b16 := &b.buckets[pos]
         .          .    654:	*b16 = bucket16{}
         .          .    655:	return b16
         .          .    656:}

This is a cpu profile for copying pointers to bucket16:

      10ms      1.14s (flat, cum)  2.19% of Total
         .      100ms    647:	b.b16his = append(b.b16his[:pos+1], b.b16his[pos:]...)
         .          .    648:	b.b16his[pos] = hi

beee24ecee vmalert: support extra_filter_labels setting per-group (#1319) 
The new setting `extra_filter_labels` may be assigned to group.
If it is, then all rules within a group will automatically filter
for configured labels. The feature is well-described here
https://docs.victoriametrics.com#prometheus-querying-api-enhancements

New setting is compatible only with VM datasource.

89e1a45cdb lib/fs: concurrently remove up to 1024 blocked NFS directories 
Previously the blocked directories were removed sequentially by a single goroutine.
This can be not enough for highly loaded VictoriaMetrics that accepts millions of sample per second,
when big number of LSM parts are created and removed at high rate.
