In order to maintain current behavior when deploying ceilometer using
the integrated release, default 'cinder_rabbitmq_telemetry_password'
to 'cinder_rabbitmq_password'. 'cinder_rabbitmq_telemetry_*' vars
may be provided by the user as overrides if a separate rabbitmq cluster
is being used for telemetry.
Also update the configured transport_urls to only include a comma
between urls and re-add rabbit configuration information to the
oslo_messaging_rabbit block.
