Escape configure Redis and RabbitMQ connection directley

[agolybev]

Use debconf params here to setup Redis and RabbitMQ connection:

Don't you think it would be more useful to just put local.json in a template? The current use of debconf makes the role not idempotent. Set up db user password always produces a change.
