4e39bf148c 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.

74963f71c6 lib/logger: explicitly import "time/tzdata" package for embedding tzdata into the app 
The approach with `timetzdata` build tag didn't work for GOARCH=arm and GOARCH=ppc64le
due to the issue https://github.com/golang/go/issues/44073#issuecomment-778854298

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

0e26b7168a lib/storage: return back in-order applying of tag filters, since concurrently executing tag filters can result in CPU and RAM waste in common case 2021-02-10 22:41:04 +02:00

b51c23dc5b lib/storage: parallelize tag filters execution a bit 
This should reduce execution time when a query contains multiple tag filters and each such filter matches big number of time series.

c7ee2fabb8 lib/storage: remove filter arg from getMetricIDsForDateTagFilter function 
The `filter` arg breaks the logic for sorting tag filters by the matching metrics,
which may result in non-optimal performance during time series search.

a4140de9e6 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.

Note that these metrics are exported only for failing scrape targets. They aren't exposed for normally working targets.
