74963f71c6 lib/logger: explicitly import "time/tzdata" package for embedding tzdata into the app

71c417427c lib/storage: sort tag filters by actual execution time instead of by the number of matching time series 
This should improve query speed for queries with regexp filters matching small number of time series
on a label with big number of unique values.

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
