Subject: [PATCH] [devstack][ci] Move bgp setup to plugin

We currently use a legacy devstack-gate script
to create the bgp speaker, and peer required
to communicate to and from the tenant private
IPv6 networks.

Move this logic to the devstack plugin so that
we can invoke it automatically with the existing
devstack variable MANILA_SETUP_IPV6.

Change-Id: Iea90e3f04ae05e5783c3163bbf2d2dabd128c7b5
(cherry picked from commit 2277c20c02641c3a0cd0804ef53a54cd5492ce2d)
