Build a KafkaThread class which wraps shutting down with interruption and exception handling; and let the leaderFinderThread, AbstractFetcherThread and RequestSendThread classes extend it.

> We have a lot of threads that basically run in a loop and use an isRunning atomic boolean and count down latch. It will be useful to refactor it out into a helper runnable that these can extend. Verifying the lifecycle details for each is kind of a pain and it pretty easy to either not cleanly shutdown all the threads.
