glance image uploads fail with ceilometer enabled

[Dave Walker]

Trying to upload an image to glance, fails with a cryptic error of not being able to find the host.

The cause seems to be a misconfigured rabbit config for glance:

AMQP server on 10.131.161.211:5672,10.131.161.203:5672,10.131.161.235:5672rabbit_userid = openstack:5672:5672 is unreachable: [Errno -2] Name or service not known. Trying again in 32 seconds.

Currently glance-*.conf has:
[oslo_messaging_rabbit]
rabbit_host = 10.131.161.211:5672,10.131.161.203:5672,10.131.161.235:5672rabbit_userid = openstack
rabbit_password = <REDACTED>

But it should have:
[oslo_messaging_rabbit]
rabbit_userid = openstack
rabbit_password = <REDACTED>
rabbit_ha_queues = true
rabbit_hosts = 10.131.161.211:5672,10.131.161.203:5672,10.131.161.235:5672

    glance-*, fix rabbit config with ceilometer

    Currently, if ceilometer is enabled with glance then the
    rabbitmq is non-functional, causing various glance failures
    including image upload.

    This is caused because:
    The generated config fails to have a carriage return at the
    end of the rabbit_host line, causing the following line to
    be added to this entry.

    rabbit_host is used rather than rabbit_hosts, where the
    fromer expects a string, rather than the list that is
    provided.

    This also adds rabbit HA support, to be in-line with the
    other services using rabbitmq.

    This is resolved, by pushing the rabbit_hosts entry to be
    last, meaning that a carriage return is not required.
