datapath: add key support to CAPWAP tunnel
Add tunnel key support to CAPWAP vport. Uses the optional WSI field in a
CAPWAP header to store a 64bit key. It can also be used without keys, in which
case it is backward compatible with the old code. Documentation about the
WSI field format is in CAPWAP.txt.
