Add gabbi-tempest unofficial project

Add basic config and access for gabbi-tempest project,
with upstream to originating project on github.

The project will not have a separate IRC channel, and makes
no distinction between core team and release team.

Gabbi-tempest is a tempest plugin that will, eventually, allow
openstack services to easily run gabbi [1] tests in a simple way.
