session: refactor local/cut-through listens
Introduce a cut-through transport as replacement to local sessions. This first patch removes the per app local listener pools and switches local listeners to sessions with cut-through transport. Change-Id: I98b20c25bc5df5f4110bf66f76c650a973032618 Signed-off-by: Florin Coras <fcoras@cisco.com>
