While I was at it, I noticed that the Neutron LBaaS requirements list LVS
under the manner in which to support UDP.
https://wiki.openstack.org/wiki/Neutron/LBaaS/requirements
So, looked for an LVS plug-in for Neutron LBaaS. I found one in progress
for Juno (which may be too late for me)... Looking at the code, it seems to
support HTTP/TCP/SSH, but I don't see UDP. Am I missing something?
