Push signals to RabbitMQ

[cdparra]

In a nutshell:

• We need to make sure we are pushing signals to RabbitMQ. An option to map signals to RabbitMQ is:
  1. Push signals to an exchange called appcivist
  2. Each resource space should be related to a queue (identified by its uuid)
  3. Use routing keys to route to the proper queue
• Let's document how are we pushing these signals to RabbitMQ (if we are) to facilitate the task of reading these push notifications from the UI. Create a Readme file inside /docs/ folder

Obs.: This is probably done better in the subscription-manager

Maybe not needed if we can read directly from rabbitmq queue
