[Francis Ginther]

Add relationship hooks for handling the jenkaas-slave relationship.

Add relationship hooks and boilerplate for handling the jenkaas-slave relationship.

This doesn't do anything useful yet, just accepts the relationship from a jenkaas-slave. install_slaves() will report:

{'jenkaas-slave': {u'jenkaas-slave:0': {'jenkaas/0': {u'private-address': u'10.25.176.81', u'master-address': u'10.25.176.81', u'port': u'48484'}, u'jenkaas-slave/0': {u'private-address': u'10.25.176.82', u'slave-address': u'10.25.176.82'}}}}
