Add "RemoveEventHandler" from informers

[csviri]

Is your enhancement related to a problem? Please describe

Would like to dynamically remove event handlers from informers.
Similarly, how it is implemented in go:
https://github.com/kubernetes/client-go/blob/3dc7fd5f4c1d8afaf5924c461eae2ab27db0045a/tools/cache/shared_informer.go#L166

Describe the solution you'd like

Similarly as in go, would like to change the return type of the function:

https://github.com/fabric8io/kubernetes-client/blob/refs/heads/main/kubernetes-client/src/main/java/io/fabric8/kubernetes/client/informers/impl/DefaultSharedIndexInformer.java#L100

to a new type ResourceEventHandlerRegistration. That could be subsequently used to remove the event handler.

@shawkins @manusa if this makes sense to you, I can take a look and implement it.

Removing handlers seems absolutely fine.

OK from my side too.
You're the ones mostly dealing with informers.
Please go ahead 🙌
