[stable-only] Drop lower-constraints job

During the PTG the TC discussed the topic and decided to drop the job
completely. Since the latest job configuration broke all stable gate
for nova (older than yoga) this is needed there to unblock our gates.
For dropping the job on master let's wait to the resolution as the
gate is not broken there, hence the patch is stable-only.

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

NOTE(elod.illes): conflict is due to branch specific settings (job
was set to non-voting, lower constraints changes, tox targets were
refactored in ussuri).
Another change in .zuul.yaml is due to requirements-check job runs now
against ubuntu-focal, that breaks tools/test_setup.sh script (fix
exists in victoria: I97b0dcbb88c6ef7c22e3c55970211bed792bbd0d). This
patch pins the job locally for ubuntu-bionic nodeset.
