Use local py2 upper-constraints

The global upper constraints repo will no longer track py2 packages,
meaning upper constraints for the py2.7 runtime will need to be handled
locally.

This adds an in-repo file for upper constraints enforcement using the
last py27 constraints from openstack/requirements to validate
functionality.
