Fix requirements (bandit, sphinx, jsonschema) and jobs

Requirements:
- bandit 1.6.0 contains a regression in the handling of patterns.
  A fix is in place in bandit master, but newer versions introduces
  more checks so they are not working as well.
  The version is excluded there because is not handled by global
  requirements.

  Remove the separate requirement file for bandit, because
  bandit has been part of test-requirements.txt in the last 3 years.
  There is noneed for a separate requirements file anymore.
  Even more, the bandit tox environment could be probably removed.

- synchronize the requirements for sphinx and jsonschema with the
  current values from the requirements repository to make
  the requirements-check job happy.

Jobs:
- temporarily disable the scenario-py3 job until a new stestr
  (>2.3.1) is tagged.
