Clean up resources

In order to avoid memory leaks, do the following to unregister a media source from the client and free the client.

try {
    kinesisVideoClient.unregisterMediaSource(mediaSource);
    kinesisVideoClient.free();
} catch (final KinesisVideoException e) {
    throw new RuntimeException(e);
}

If you added any items to the cache using the CachedInfoMultiAuthServiceCallbacks, for example:

serviceCallbacks.addStreamInfoToCache(streamName, streamInfo);
serviceCallbacks.addStreamingEndpointToCache(streamName, dataEndpoint);

Clear the cache when you're done:

serviceCallbacks.removeStreamFromCache(streamName);
