Subject: [PATCH] Add Octavia file in devstack/lib

Looks like this was initially missed on the OVN migration,
but after talking with Octavia, this setup should really
all live here since it's SDN-specific things that are
being configured.

Content basically copied from the octavia devstack/plugin.sh
script with some small modifications to support OVN.
