512addc608 app/{vminsert,vmagent}: add -sortLabels command-line option for sorting time series labels before ingesting them in the storage 
This option can be useful when samples for the same time series are ingested with distinct order of labels.
For example, metric{k1="v1",k2="v2"} and metric{k2="v2",k1="v1"}.

Aliaksandr Valialkin
587132555f lib/mergeset: reduce memory usage for inmemoryBlock by using more compact items representation 
This also should reduce CPU time spent by GC, since inmemoryBlock.items don't have pointers now,
so GC doesn't need visiting them.

bd3bcdc43c lib/storage: do not re-calculate stats for heavy tag filters

b8a5ee2e93 lib/{mergeset,storage}: allow merging smaller number of small parts 
While this may increase CPU and disk IO usage needed for background merge,
this also recudes CPU usage during queries in production. This is because
such queries tend to read recently added data and it is better to have lower number
of parts for such data in order to reduce CPU usage.

2005d8212a lib/storage: return back filter arg to getMetricIDsForTagFilter function 
The filter arg has been removed in the commit c7ee2fabb8
because it was preventing from caching the number of matching time series per each tf.

Now the cache contains duration for tf execution, so the filter shouldn't break such caching.

9e3993c585 lib/storage: properly hanle regexp tag filters with dots, which can be converted to full string match filters.

c736339843 lib/{storage,mergeset}: clean cached index blocks and inmemory blocks more aggressively 
Previously such blocks were cleaned after they weren't accessed during 10 minutes.
Now they are cleaned after one minute of missing access. This should reduce memory usage in general case.

fd7dd5064a lib/storage: code cleanup after 10f2eedee0 
Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search,

While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names
such as `foo.bar.baz`).

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.
