Enable TLS configuration for containerized RabbitMQ

In non-containerized deployments, RabbitMQ can be configured to use TLS for
serving and mirroring traffic.

Fix the creation of the rabbitmq bundle resource to enable TLS when configured.
The key and cert are passed as other configuration files and must be copied by
Kolla at container startup.
