A long time ago, oslo-incubator had a lot of code, we have made most
of the code to oslo.* libraries. There's very little code left and
we'd like to stop hosting common code in oslo-incubator repository. We
encourage everyone to adopt the code they have in their repos under
openstack/common into their own namespace/packaging as we will be
getting rid of any remaining python modules in oslo-incubator.
If there are a couple of projects sharing code, like say cinder and
manila (HT to bswartz), one of those projects can choose to host a
common library between them, similar to how nova and cinder share
os-brick with its own core team. The overall guide to starting
projects is documented here  so you will needs bits of that for
existing projects. when in doubt, look in governance, project-config,
requirements repos and model your own.
