727ded9d4e lib/storage: time series search optimization according to production workload profiling 
Do not pass filter metric ids to getMetricIDsForTagFilter, since it has been appeared that this slows down
the function by multiple times when it finds big number of metricIDs (tens of millions).

7f52aae20c lib/promscrape: an attempt to reduce memory usage when vmagent scrapes targets with varying number of metrics 
Do not cache too big byte buffers and too big writeRequestCtx objects,
since it is cheaper to re-create them instead of wasting RAM for their caching.

8fc29ffc67 lib/promscrape/discovery/kubernetes: use a single watcher per apiURL 
Previously multiple scrape jobs could create multiple watchers for the same apiURL. Now only a single watcher is used.
