The base prefix added on to the listener classes is not very useful and is already understood that these are base classes by documentation or abc.ABCMeta usage so we don't need to specifically name these classes bases to also show that they are a base class (useless duplicate information). So in this change we deprecate the 'ListenerBase' and the 'LoggingBase' and rename these classes to more appropriate names. Change-Id: Iaeaeaf698c23d71720ef7b62c8781996829e192a
