a22f37599b lib/storage: tune tag filters search logic 
Tune the logic according to the logs provided at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-864293624

The previous logic had a race when multiple concurrent queries execute the same tag filter without prior stats.
This could result in incorrectly stored stats for such tag filter, which then could result in non-optimal sorting of tag filters
for further queries.

0efd37cec1 lib/{mergeset,storage}: reduce the number of fsync calls on data ingestion path on systems with many cpu cores 
VictoriaMetrics maintains a buffer per CPU core for the ingested data. These buffers are flushed to disk every second.
These buffers are flushed to disk in parallel starting from the commit 56b6b893ce .
This resulted in increased write disk IO usage on systems with many cpu cores
as described at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-863046999 .

This commit merges the per-CPU buffers into bigger in-memory buffers before flushing them to disk.
This should reduce the rate of fsync syscalls and, consequently, the write disk IO on systems with many CPU cores.

This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338

b133de1e37 lib/storage: move deletedMetricIDs set from indexDB to Storage 
This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB).
This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation.
See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 .

Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart.
This should be OK in most cases.

0672cfffa2 app/vmauth: properly handle http.ErrAbortHandler panic 
This panic can be raised by the reverseProxy on aborted request to the backend.
So handle it (e.g. suppress) at reverseProxy.ServeHTTP call.

Do not suppress the panic at lib/httpserver generic HTTP handler,
since it may result in an inconsistent state left after the panicking handler.

* new feature: relabel logging

Use scrape_configs[x].relabel_debug = true to log metric names inkl.
labels before and after relabeling. After relabeling related metrics
get dropped, i.e. not submitted to servers.

* vminsert wants relabel logging, too.

7b33bc67a1 lib/mergeset: remove a pool for inmemoryBlock structs

while it may result in excess memory usage for inmemoryBlock structs inside the pool during
background merge of indexdb.

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
