Speaking to Devananda about the copy of the code in Ironic, he made the
case that Ironic was just going to sync the code from Nova without
making modifications to it until the code was ready to graduate as a
standalone library or move to oslo-incubator.

That actually does make some sense - I've often described oslo-incubator
as "managed copy and paste". It still sucks, but not as much as the copy
and paste we've done previously where the multiple copies of the same
code evolved independently.

Now, in the case of this Solum import, it does look like this is a fork
of the Nova code. Unless there's some realistic plan to reconcile these
forks, then I think it is a problem and quite short-sighted.
