> Currently we can only bind a JMS destination using one key. But there are use cases where
you may need to bind a queue using different binding keys to consume messages from different
sources.
> The JMS Destination provides an abstraction to hide provider details. But from AMQP POV,
a JMS destination has a dual nature.
> For a producer a destination represents a exchange/routingkey pair.
> For a consumer a destination should represent a queue and multiple bindings. 
> (Ideally it should be an array of the following tuple {exchange,queue,binding}, but this
is difficult to express using a simple URL ).
> A single destination can be used for publishing, consuming or both, so we need our URL
to capture all 3 use cases.
> Using the 0-10 protocol we can introduce a bindingKey option that contrains a coma separated
binding keys as follows.
> Ex: Destination used only for publishing
> ------------------------------------------------------
> destination.myQueue = direct://amq.direct//myQueue?routingkey='stock'
> Ex: Destination used only for consuming
> -------------------------------------------------------
> destination.myQueue = direct://amq.direct//myQueue?bindingkey='car,van'
> (This binds a queue to the direct exchange twice using car and van as binding keys)
> Ex: Destination used for both consuming and publishing
> ------------------------------------------------------------------------------
> destination.myQueue = direct://amq.direct//myQueue?routingKey='vehicle'&bindingkey='car,van'
> (This binds a queue to the direct exchange twice using car and van as binding keys for
the consumer, and will when the publisher uses it, it will push a message to the direct exchange
with the routingKey vehicle)
> This has to be backward compatible with old URLs and optimized for the common case where
only a routing key is specified. In such a case the routiing key is also used as the binding
key
