> Although 0-x specifies a "no-name" default "exchange" that behaves like a direct exchange
where the queues are bound to the exchange with a binding-key equal to the queues name...
Given the advent of 1-0 it is perhaps more consistent to think of it as a "routing node" which
will take whatever is in the routing key of the inbound transfer and use that to route to
the appropriate destination (whether this be a queue or another node).
> As a first step to implementing this, we should change the implementation detail internally
such that the "default exchange" is not presented in the set of "Exchanges" and doesn't implement
the Exchange interface.
> For 0-x protocols we can "fake" it's existence as an exchange for operations such as
exchange declare / delete / bind / unbind / query
