The deletion of the primary IP via the ip command will also remove the secondary IP. Thus, trying to delete the secondary IP after the primary IP was deleted will result in an error. This fix assures that delete_interface() will only result in an error if ' addr delete' has failed and the ip is still listed in  addr show.
Adds the RA for the redis service, based on that of mysql. Supports master/slave configurations of a depth of 1.
