fd86a7dc1d 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).

c14dafce43 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.

3fd8653b40 lib/promscrape: apply sample_limit after metric relabeling is applied as Prometheus does 
See the description for `sample_limit` option from Prometheus docs:

Per-scrape limit on number of scraped samples that will be accepted.
If more than this number of samples are present after metric relabeling
the entire scrape will be treated as failed. 0 means no limit.

ab4f090c63 lib/promscrape/discovery/kubernetes: reduce memory usage further when big number of scrape jobs are configured for the same kubernetes_sd_config role 
Serialize reloading per-role objects, so they don't occupy too much memory when objects for many scrape jobs are simultaneously refreshed.
Do not reload per-role objects if they were already refreshed by concurrent goroutines. This should reduce load on Kubernetes API server
when big number of scrape jobs are configured for the same Kubernetes role.

17b87725ed lib/promscrape/discovery/kubernetes: reduce memory usage when Kubernetes service discovery is configured on a big number of scrape jobs 
Previously vmagent was creating a separate Kubernetes object cache per each scrape job.
This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.)
as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113

Now it uses a shared map of scrape objects across multiple scrape jobs.

* rollback separator

* Adds windows setInformation api,
it must behave like unix, need to test it.
changes procutil

* check for invlaid param

* Fixes posix delete semantic

* refactored a bit

* fixes openbsd build

* removed windows api call

* Fixes code after windows add

While this may increase CPU and disk IO usage needed for background merge,
this also recudes CPU usage during queries in production. This is because
such queries tend to read recently added data and it is better to have lower number
of parts for such data in order to reduce CPU usage.

faad6f84a4 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.
