e05dd475f0 lib/fs: concurrently remove up to 1024 blocked NFS directories 
Previously the blocked directories were removed sequentially by a single goroutine.
This can be not enough for highly loaded VictoriaMetrics that accepts millions of sample per second,
when big number of LSM parts are created and removed at high rate.

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.
