Disable in-band control for PUBLIC_BRIDGE

By default, Open vSwitch installs internal flows for in-band control
to bridges with controller setting.  "with controller setting" part
is false for openvswitch agent but can be true for ofagent.
Unfortunately the internal flows are incompatible with our use of
the local port here to communicate with neutron router.  This commit
avoids the problem by disabling the in-band control functionality.

Add a MAINTAINERS.rst file with two goals

1) to help seed initial reviews with relevant people.  Devstack by its
nature attracts new contributors, so when they hit some obscure bug,
this will help them find out who to put on a review.

2) core reviewers can't know everything about everything.  Having
someone who has flagged themselves as interested in an area sign-off
off on relevant changes can help move changes through.
