Re-Add oslo.middleware namespace for backward compat3.2.0

Short Story:
If we don't do this then we have to drop,
assert:support-upgrade from nova (Really Really Bad!)

Longer Story:
We need to support kilo paste-ini until liberty-eol per policies
already in place. To do that an alternative would have been
to cap global-requirements, but that got ruled out, please
see work and reasons here:
I5731b0278e266699fe716733b6dd4f7238a35586

There's also another new spec openstack-specs that is gathering
a lot of positive votes regarding backward compat:
I72e4e9cfa0539f6b326a0296c065fa3cb754f8ae

Note that this is not a straight revert of:
I1479f37f500a358cdf7ad416f0257288b65c9245

As i just want to drop the tests and keep the files to a
minimum. The grenade job is enough to test the older
scenario (which was failing) which we need to support.
