Enable functional convergence testing

This commit updates tests/test.yml to deploy rabbitmq, galera,
keystone, and cinder for a functional convergence test.  Note that we
point at a non-existent memcached server, but this can be adjusted to
build memcached if deemed necessary. Additionally, we do not configure
a cinder-volume backend, but simply deploy the service itself. This is
something that can be tweaked in a later revision.
