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.

This partially reverts ebf8da3730

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. 
For example `{label=~"foo\.bar"}` should be converted to `{label="foo.bar"}`. Previously it has was mistakenly conveted to `{label="foo\.bar"}` .

18c2075159 lib/promscrape: remove vm_promscrape_scrapes_failed_per_url_total and vm_promscrape_scrapes_skipped_by_sample_limit_per_url_total metrics

* It is better using `up == 0` query for determining failing targets.
* It is better using the following query for determining targets with exceeded limit on the number of metrics:

  scrape_samples_scraped > 0 if up == 0

could prevent from releasing memory occupied by all the ScrapeWork items stored in the slice when they
are no longer used.
