Relabelling rules can use this information to attach the name of the controller
that has created a pod.
In turn, this can be used to slice metrics by workload at query time, ie.
"Give me all metrics that have been created by the $name Deployment"

- Do initial listing and syncing to scrape manager, then register event
handlers may lost events happening in listing and syncing (if it
lasted a long time). We should register event handlers at the very
begining, before processing just wait until informers synced (sync in
informer will list all objects and call OnUpdate event handler).
- Use a queue then we don't block event callbacks and an object will be
processed only once if added multiple times before it being processed.
- Fix bug in `serviceUpdate` in endpoints.go, we should build endpoints
when `exists && err == nil`. Add `^TestEndpointsDiscoveryWithService`
tests to test this feature.
Testing:
- Use `k8s.io/client-go` testing framework and fake implementations which are
more robust and reliable for testing.
- `Test\w+DiscoveryBeforeRun` are used to test objects created before
discoverer runs
- `Test\w+DiscoveryAdd\w+` are used to test adding objects
- `Test\w+DiscoveryDelete\w+` are used to test deleting objects
- `Test\w+DiscoveryUpdate\w+` are used to test updating objects
- `TestEndpointsDiscoveryWithService\w+` are used to test endpoints
events triggered by services
- `cache.DeletedFinalStateUnknown` related stuffs are removed, because
we don't care deleted objects in store, we only need its name to send
a specical `targetgroup.Group` to scrape manager
