* Reworked tox pep8 into linters job, that runs:
  - pep8
  - bandit
  - bashate
  - doc8
  - yamllint
  - ansible-lint (validate-all-files.py + ansible-lint)

* Skip E701 - missing galaxy_info in meta and E602 see [1].
* Skip E301 and E503 - followup later in a separate change
* Added ansible-role-jobs to zuul.d/project.yaml which will run
  openstack-tox-linters job in check queue
* Fixed remaining style issue
* Made tox and docs reference the new env for linters
* Dropped pype environment (not supported)
