Multi-Tenanted Rabbit MQ & Azure Service Bus connections

For a JasperFx client.

What we need for both Azure Service Bus & Rabbit MQ (for now) is the ability to specify a separate Azure Service Bus namespace or Rabbit MQ virtual host for different tenant ids.

Going well right now. Do need to add a way to "tell" individual queues or endpoints that they should opt out of being multi-tenanted
