> Temporary destinations are typically used to receive response messages in
> a request/response messaging exchange.  A temporary destination can only
> be consumed by a subscription created on the connection which is associated
> with the temporary destination.  Once the connection is closed, all associated
> temporary destinations are removed. Temporary destinations are prefixed with:
> * `/temp-queue/` - For temporary queues.  Has the same delivery semantics as queues.
> * `/temp-topic/` - For temporary topics.  It has the same delivery semantics of topics.
> In a request/response scenario, you would first subscribe to the temporary topic:
>     SUBSCRIBE
>     id:mysub
>     destination:/temp-queue/example
>     
>     ^@
> Then you would send a request with the reply-to header set to the temporary destination.

> Example:
>     SEND
>     destination:/queue/PO.REQUEST
>     reply-to:/temp-queue/example
>     PO145
>     ^@
> The consumer receiving the request will receive a message similar to:
>     MESSAGE
>     subscription:foo
>     reply-to:/queue/temp.default.23.example
>     destination:/queue/PO.REQUEST
>     reply-to:/temp-queue/example
>     
>     PO145
> Notice that the reply-to` header value is updated from a temporary destination
> name to normal destination name.  The subscription servicing he requests should respond
> to the updated destination value (`/queue/temp.default.23.example` in the example above).
> Temporary destination names actually map to normal queues and topics. They just have
> a `temp.<broker_id>.<connection_id>.` prefix.  Any destination which starts
with
> `temp.` has a security policy which only allows the connection which created it
> to subscribe from it.  These destinations are also auto deleted once the connection
> is closed.
> Provides a better fix for APLO-86 and removes support for the 'temp:true' header on the
subscribe frame.
