Stop testing lower-constraints

[1] http://lists.openstack.org/pipermail/openstack-discuss/2020-October/018445.html

Conflicts:
  .zuul.yaml
  bindep.txt
  lower-constraints.txt
  tox.ini

NOTE(stephenfin): Conflicts are due to the changed job template (train
vs ussuri), slightly different lower constraints between branches and
presence of a 'basepython' line in the tox environment. The bindep
change added to the stable/ussuri change is no longer relevant here.
