RabbitMQ official driver support

[valehasadli]

Hi, dear @taylorotwell and Laravel family. The first thanks for this super powerful framework.

I would like to see RabbitMQ queue driver support. I think it would be better to have official support because there is an official image in https://hub.docker.com/. And it makes an easy, find a solution very fast. For example, Laravel supports Beanstalkd, but there is no official image in https://hub.docker.com
