A class for receiving HMC notifications that are published to particular

**Experimental:** This class is considered experimental at this point, and

Creating an object of this class establishes a JMS session with the
HMC and subscribes for the specified HMC notification topic(s).
Notification topic strings are created by the HMC in context of a
particular client session (i.e. :class:`~zhmcclient.Session` object).
However, these topic strings can be used by any JMS message listener that
knows the topic string and that authenticates under some valid HMC userid.
