session: support for cl port reuse
Adds support for connectionless listener port reuse. Until now, cl
listeners had fifos allocated to them and therefore only one app worker
could ever listen, i.e., a session cannot have multiple fifos.
To circumvent the limitation, this separates the fifos from the listener
by allocating new cl sessions for each app worker that reuses the app
listener. Flows are hashed to app worker cl sessions but, for now, this
is not a consistent/fixed hash.
Type: improvement
