While working on https://review.openstack.org/#/c/320542/, galera was found to be listening only on IPv6 addresses. Connections to ::1 worked fine, but connections to 127.0.0.1 failed. This patch ensures that galera is listening on all IPv4 and IPv6 addresses. Closes-bug: 1620793 Change-Id: I1ddae03343b6fe9542b6118810cc55108d4417c0
