James Page 54530ab595 Refactor RabbitMQ integration
Prior to this change, the ceilometer-agent charm receives RMQ
configuration details via the ceilometer charm.  This makes it
a bit of a snowflake.

Refactor RMQ integration to require a direct relation to the
rabbitmq-server charm; information provided on this relation
will superceed any information currently provided via the
charms relation with ceilometer, ensuring that there is no
disruption to service during a charm upgrade before the new
relation is added.

Switch to using [DEFAULT]transport_url for RMQ configuration,
making use of the new ch template for SSL and HA configuration
in [oslo_messaging_rabbit].
