ARTEMIS-4279 Shutdown critical analyzer thread if error on broker initialization

The broker process fails to exit if an error is encountered starting the NodeManager.  The issue is resolved by converting the critical analyzer thread to a daemon thread.  As added protection, the thread is manually stopped when this error is encountered.
