This metric should work better than the filter execution duration, since it cannot be distorted
by concurrently running queries.

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.

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
