Remove unused _forceRebalanceTimer from GenericHelixController `GenericHelixController. _forceRebalanceTimer` is a non-daemon `Timer` thread. It is started in the initializer of `GenericHelixController` and never shut down. This causes process JVM shutdown to never finish as this thread is hanging. However, ` _forceRebalanceTimer` is never actually used for anything. I propose fixing the issue by removing the timer thread entirely.
