    This might not work correctly.  If two streams are running on the same JVM, this will clear out both streams JMXbeans.

> As a Streams developer, I should be able to run multiple Streams in a serial fashion without issue. Currently, JMX beans (which are used for monitoring the Stream's activity) are not cleared when a Stream is shutdown. If a new Stream is started afterwards (without a JVM restart) then there is a collision in the naming of the JMX beans which causes an exception which shuts down the subsequent Stream. Need to build in functionality to clear all JMX beans on shutdown.
