Description

The HA module formerly loaded and initialized even if there were no --ha options set. This can cause conflicts with other modules, in particular the old active-active cluster module (see https://bugzilla.redhat.com/show_bug.cgi?id=885658)

This patch initializes the HA module only if one of --ha-cluster or --ha-queue-replication is set.
--ha-cluster has the same meaning as before. --ha-queue-replication enables queue replication without joining a cluster - this was the old behaviour if no --ha options were set.
