Creating and passing an AMQP connection in config

[ionutzp]

Hello all, @jondot
I am trying to implement Sneakers in an existing web application and I am trying to reuse an existing amqp connection. I've passed it in the connection as a configuration option:

Sneakers.configure(
  connection: InstantiateAMQPConnection,
  heartbeat: 30,
...

I'm getting a timeout and i think it's related to the forking for Sneakers:

Unexpected error Timeout::Error

That means that it would be safer to pass connection details so that each worker can open their own connection to rabbit? (lib/sneakers/worker.rb)
