Dropping lower constraints testing

We facing errors related to the new pip resolver, this
topic was discussed on the ML and QA team proposed to
to test lower-constraints [1].

I propose to drop this test because the complexity and recurring pain needed
to maintain that now exceeds the benefits provided by this mechanismes.

Also removing lower constraints and related tox environment as they are
no longer needed.

Conflicts:
  .zuul.yaml
  lower-constraints.txt

NOTE(hberaud): Conflicts are due to different base jobs in zuul and
different constraints in lower-constraints
