hmm. what-if we open this framework to a wider audience? For instance,
openshift folks might be interested in some validations (I have Ceph in
mind), and might find weird or even bad to have "tripleo-something"
(with underscore or dashes).
Maybe something more generic?
"vf(-nova)" ?
"validation-framework(-nova)" ?
Or even "opendev-validation(-nova)"
Since there are also a possibility to ask for a new package name for
something more generic without the "tripleo" taint..
