Add JSON for initializing RabbitMQ

values, useful for testing in a development environment.

These settings are unsafe and only meant to be used in

Add basic support for publishing to an AMQP backend

Add basic functionality to the AMQP Worker:
* Set up connection to AMQP backend at startup, and keep
  it open during the whole lifecycle
* Send an arbitrary message to an AMQP exchange

This is still very rudimentary and a log of sanity checks
are still missing, but it's able to publish messages, which
is the bare minimum.

Wait for message confirmation

After sending a message, read from AMQP channels to get proper
delivery confirmation, and report back.
