Get ready to vomit.

The lbaasv2 code you’re pulling is a non-agent driver.  Meaning, it runs
haproxy on the *neutron controller* node, and only the controller node.
It’s meant to be a POC for single node systems, not something you can
deploy.

In the upcoming mid-cycle, the driver will be agent-ified, like v1. I
believe Phil from Rax will be leading that effort.

Thanks,
Doug
