If you want to re-use the same Channel when calling a remote TCP server with netty producer, then this requires to store the Channel on the exchange so it can be re-used on the next netty producer and so on. And then use an UoW to return the Channel in the pool when the Exchange is done.

For example in the route below, the 2 x netty should use the same Channel.

from foo
to netty
to bar
to netty
