udp: fix for multiple workers and add test
Since the main thread is not used for session polling anymore, when vpp is started with multiple wokers, allocate connections on the first. Also add a simple udp make test. Change-Id: Id869f5d89e0fced51048f0384fa86a5022258b7c Signed-off-by: Florin Coras <fcoras@cisco.com>
