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.

So or so i need a converter from the output format to a hash:
a examples: 
* a empty hash: `[]`
* a not empty hash: `[{"x-message-ttl",55},{"x-dead-letter-exchange","mycatchexchange"}]`

if you what it than i can write a converter method for this output to a hash without JSON.
I use JSON only for the reason that i need JSON for the create.
