3062ff0fdb app/vmselect: export per-tenant stats on the number of requests and the cumulative request duration 
The metrics are:
- vm_vmselect_http_requests_total{accountID="...",projectID="..."} - the total number of select requests per each tenant
- vm_vmselect_http_duration_ms_total{accountID="...",projectID="..."} - the total duration in milliseconds for per-tenant select requests

46e98ed490 vendor: update github.com/VictoriaMetrics/metrics from v1.13.1 to v1.14.0 
The new version switches from log-linear histograms to log-based histograms,
which provide up to 3.6 times better accuracy.

54a09de037 lib/logger: explicitly import "time/tzdata" package for embedding tzdata into the app

6f3bbf21b8 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.

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

18c2075159 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

4262c2f7c2 lib/storage: remove filter arg from getMetricIDsForDateTagFilter function

which may result in non-optimal performance during time series search.

7b7963a77f lib/mergeset: unconditionally cache indexdb blocks 
Production workloads show that indexdb blocks must be cached unconditionally for reducing CPU usage.
This shouldn't increase memory usage too much, since unused blocks are removed from the cache every two minutes.
