Michele Baldessari 9e5153e909 Configure keepalived before rabbitmq 
Sometimes an undercloud could fail to install with the following error:
2018-05-29 12:53:17,588 INFO: May 29 12:53:08 foo.int.bar systemd[1]: Starting RabbitMQ broker...
2018-05-29 12:53:17,588 INFO: May 29 12:53:11 foo.int.bar rabbitmq-server[14327]: ERROR: epmd error for host foo: address (cannot connect to host/port)
2018-05-29 12:53:17,588 INFO: May 29 12:53:11 foo.int.bar systemd[1]: rabbitmq-server.service: main process exited, code=exited, status=1/FAILURE

1) The hostname of the box is
foo.int.bar foo

and in the hosts file we have the following entry: 192.168.248.2
192.168.248.2 foo.int.bar foo

Note: 192.168.248.2 is a VIP managed by keepalived because we configured this
undercloud to be an SSL one so we have:
undercloud_public_host = 192.168.248.2

2) At this stage we see rabbitmq-server being started:
Jan 27 06:46:31 foo.int.bar systemd[1]: Starting Flexible Branding Service...
Jan 27 06:46:31 foo.int.bar systemd[1]: epmd@0.0.0.0.socket failed to listen on sockets: Address already in use
Jan 27 06:46:31 foo.int.bar systemd[1]: Failed to listen on Erlang Port Mapper Daemon Activation Socket.
Jan 27 06:46:31 foo.int.bar systemd[1]: Unit epmd@0.0.0.0.socket entered failed state.
Jan 27 06:46:31 foo.int.bar systemd[1]: Starting Erlang Port Mapper Daemon Activation Socket.
Jan 27 06:46:31 foo.int.bar systemd[1]: Starting RabbitMQ broker...
Jan 27 06:46:34 foo.int.bar rabbitmq-server[14532]: ERROR: epmd error for host foo: address (cannot connect to host/port)

Now epmd might have already been up (and normally the failed message is
not particularly concerning). But the real problem is that we are trying
to connect to foo which maps to a VIP, but the VIP gets started only
later by keepalived:
3)
Jan 27 07:02:30 foo.int.bar Keepalived_vrrp[914]: VRRP_Instance(42) Sending/queueing gratuitous ARPs on br-ctlplane for 192.168.248.2
Jan 27 07:02:30 foo.int.bar Keepalived_vrrp[914]: Sending gratuitous ARP on br-ctlplane for 192.168.248.2

Let's make sure keepalived is up and running before rabbitmq in order to
fix this.
