Update TOX/UPPER_CONSTRAINTS_FILE for feature/nats-driverfeature/nats-driver

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 feature/nats-driver branch, tests will
continue to use the upper-constraints list on master.
