Support for Dynamically Stopping Runnables in Manager

[Gomaya]

The controller-runtime manager provides the ability to dynamically add and start runnables at runtime using the Add() method. However, it currently lacks a mechanism to stop or remove specific runnables dynamically once they are running.

This functionality is vital in use cases where resources, such as Kubernetes clusters, are retired, requiring their associated runnables to be gracefully stopped without affecting the rest of the manager’s operation.

Request:
Introduce support for dynamic stopping of runnables to enhance the flexibility and robustness of the manager.

Thank You
Looking forward to your insights and guidance!

However, it currently lacks a mechanism to stop or remove specific runnables dynamically once they are running.

The manager can't really find out when you want something to be stopped. Wrap your runnable with something that injects a custom context that you can cancel.
