The solution is a little unconventional though so it will need some
feedback. What it does is to do a standard python install then
duplicate the egg-info directory and manipulate it to resemble a dedicated
tempest plugin package.

I like that as a workaround for in-tree tempest plugins but proper
solution is really that upstream project creates a separate repo for
their tempest plugin. Is that in progress for Heat?
