Previously, the registry_host parameter was not exposed to the openstack::controller class. This prevented the class from managing the parameter. The new parameter glance_registry_host was added to allow users to manage the IP address used by the Glance API service for communicating with the Glance Registry service. Defaults to '0.0.0.0' for backwards compatibility. Change-Id: Ica07c59ab6ad02a825f67abd6bde5f1043993ac3
