10a47af631 app/{vmalert,vmauth}: explicitly set MaxIdleConnsPerHost in net/http.Client.Transport 
By default MaxIdleConnsPerHost is set to 2. This limits the possibility to re-use http keep-alive connections.

ce9e163e94 lib/httpserver: stop the process on panics in request handlers 
Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic
instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers.
See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.

f010d773d6 lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access 
Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets,
which depend on pod and service objects.

There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change,
since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain
ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113

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

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.
