Update the URL to the upper-constraints file to point to the redirect
rule on releases.openstack.org so that anyone working on this branch
will switch to the correct upper-constraints list automatically when
the requirements repository branches.

Until the requirements repository has as unmaintained/2023.1 branch, tests will
continue to use the upper-constraints list on master.

This patch resolves the issues with the gate by passing the tests
that are trying to use the old keystoneauth plugins. This is not
the correct fix, but it get's us past the gate issues. We need to
look at deprecating python-keystoneclient.
