python-cinderclient-functional-py39 job has been failing since
23 November, 2022[1]. The failure has been described in detail
in the mailing thread replies[2][3].
In summary, a new iSCSI target path was added in the kernel,
/sys/kernel/config/target/iscsi/*cpus_allowed_list*, which
is causing rtslib-fb 2.7.4 to fail. This issue was fixed in
rtslib-fb 2.7.5 but the upper-constraints in stable/yoga branch
is 2.7.4[4]. This isn't a problem in stable/zed since the version
used for rtslib-fb is 2.7.5[5].

I have proposed a requirements patch to bump the rtslib-fb version
to 2.7.5[6] and tested it against cinderclient[7] where the
python-cinderclient-functional-py39 job is passing.

I've tried reaching out to the requirements team on IRC and on ML
to make this change but there hasn't been any response.
The best way to move forward and unblock our gate is to skip the
failing test test_backup_create_and_delete and unblock changes
in the stable/yoga branch.

Continue to use tox 3 in the stable branches.

Two changes:
- .zuul.yaml: set the ensure_tox_version to use <4, which will
  tell zuul to install tox<4 if it's not present
- tox.ini: set requires=tox<4 so that if tox has been installed
  already, our tox-based jobs will use tox 3 to run the tests

(cherry picked from commit 22a3169576b3fd91388e7b57ffd39e3760016796)

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 stable/yoga branch, tests will
continue to use the upper-constraints list on master.

We don't need to track this in test-reqs for
unit tests, etc. since it's only used for
functional tests.
