Add new Resources for Queue and Bindings.

I Add the two new resources ``rabbitmq_queue`` and ``rabbitmq_binding``.
So it will be also possible to manage queues and bindings between queue and exchange with puppet.

I don't write getters or setters for the reason that bindings can only create or deleted in RabbitMQ. Existing bindings can not be changed. Also exchanges and queues can only create or delete but not change.
