e540c02014 lib/storage: prevent from running identical heavy tag filters in concurrent queries when measuring the number of loops for such tag filter. 
This should reduce CPU usage spikes when measuring the number of loops needed for heavy tag filters

711f8a5b8d lib/storage: sort tag filters by the number of loops they need for the execution 
This metric should work better than the filter execution duration, since it cannot be distorted
by concurrently running queries.

faad6f84a4 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.

c727d2219b 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"}` .
This could result in missing time series for such tag filters.

80dc74dbc1 lib/promscrape: remove vm_promscrape_scrapes_failed_per_url_total and vm_promscrape_scrapes_skipped_by_sample_limit_per_url_total metrics 
These metrics may result in big number of time series when vmagent scrapes thousands of targets and these targets constantly changes.

* 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
