server: Remove Association.__getattr__

Refactor the Association class in preparation for inheriting
from obmc.dbuslib.DbusProperties.

 - Remove the __getattr__ override and its usage.  It does not
appear to be necessary.
 - Store endpoints in an interface/properties dictionary named
properties in alignment with obmc.dbuslib.DbusProperties.
 - Refactor methods to use properties dictionary rather than the
endpoints list.
