9da2ef3d8f lib/promscrape/discovery/kubernetes: load objects missing in local cache from api seriver in getObjectByRole() 
This should fix possible race for `role: endpoints` and `role: endpointslices` service discovery,
when the referred `pod` and `service` objects aren't propagated to urlWatcher cache yet.

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1182#issuecomment-813353359 for details.

fe084fdd33 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.
