shutdown to guarantee termination

shutdown to guarantee termination

This method will ensure that once the shutdown sequence is
started, it terminates either gracefully or forcefully after
the grace time period expiration.

It has been occassionally observed that the shutdown
sequence gets stuck in the shutdown sequence of a subcomponent,
such as a drools applications.   This will guarantee that
the shutdown completes regardless.
