Comment 10 for bug 1811004

So the error I am looking at from comment 9 is the following:
 =ERROR REPORT==== 14-Jan-2019::09:08:48 ===
 Error on AMQP connection <0.1233.0> (192.168.24.1:52856 -> 192.168.24.1:5672, state: starting):
 AMQPLAIN login refused: user 'guest' - invalid credentials

From http://logs.openstack.org/98/604298/176/check/tripleo-ci-centos-7-scenario003-standalone/b2d7fd7/logs/undercloud/var/log/config-data/nova/etc/nova/nova.conf.txt.gz we see:
transport_url=rabbit://guest:<email address hidden>:5672/?ssl=0

The password for the guest user in used by nova is 'kSBh78C58WIEt0esxvEfkcRpM'. On the rabbit side of things we have in http://logs.openstack.org/98/604298/176/check/tripleo-ci-centos-7-scenario003-standalone/b2d7fd7/logs/undercloud/var/log/config-data/rabbitmq/etc/rabbitmq/rabbitmq.config.gz the following:
    {default_user, <<"guest">>},
    {default_pass, <<"kSBh78C58WIEt0esxvEfkcRpM">>}

So the password on both sides *seems* correct.

Ah so I think the issue is this in nova.conf:
[oslo_messaging_notifications]
driver=noop
transport_url=rabbit://guest:<email address hidden>:5672/?ssl=0

[DEFAULT]
...
transport_url=amqp://guest:<email address hidden>:31459/?ssl=0

I don't think we should be using 'amqp' here (it's late, and this needs double-checking). We should change the line at https://github.com/openstack/tripleo-heat-templates/blob/master/ci/environments/scenario003-standalone.yaml#L15 to the rabbit counter part
