Add accessbot for #openstack-fwaas

The Neutron FireWall-as-a-Service team is diverging a bit from the rest
of the Neutron team, and will soon be holding a virtual mid-cycle.  In
order not to clutter the overall #openstack-neutron channel, and to
serve the FWaaS team as it continues to diverge from Neutron, we would
like the #openstack-fwaas channel logged.
