Nice.  :-)

So, a couple of next steps after devstack can use gantt.

1) Add a patch to openstack-dev/devstack-gate for it.  We need to be
able to feed an option into devstack-gate for a CI job that uses gantt.
 devstack-gate should do the things you list here.

2) Create an experimental job in openstack-infra/config that uses gantt.
 This should be like the full tempest job, but with the option to
devstack-gate to use gantt.  We should set this up in the experimental
pipeline for nova so that we can run it on nova patches with "check
experimental" without really disrupting anyone else.

I can take a stab at these, but would be even happier if someone beats
me to it.  :-)
