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.

Seems like there would be value to use the same syntax as the policy provider for identifying vhosts: https://github.com/puppetlabs/puppetlabs-rabbitmq/blob/master/lib/puppet/provider/rabbitmq_policy/rabbitmqctl.rb#L49
