Tox 4.0.0 has some incompatible changes, epecially more
strict on allowlist_externals. Tempest recently changed
allowlist_externals not to be *[1] causing the failure
on jobs where lib/tempest failing to run the tempest
as command in virtual env.
----------
venv: commands[0]> tempest verify-config -uro /tmp/tmp.qH5KgJHTF4
venv: failed with tempest is not allowed, use allowlist_externals to allow it
------
We do not need to test/fix the <=stable/zed branches with tox 4.0.0
and pinning them with the compatible tox version of the time stable
brnaches were releaased is better way.
This commit proposes:
1. Pinning the tox<4.0.0 for <=stable/ze branches testing
2. Workaround to unblock the master gate by pinning it <4.0.0 but
we should make our testing compatible with tox 4.0.0 soon.
