    Fixes and addition for the API and CLI tests.

    Support for CDH 5.9 in scenario tests.

    Less parameters required for scenario tests.
features:
  - The Tempest-based tests have received an increase of the coverage
    for both API and CLI tests (job, plugins, templates; negative
    testing).
  - CDH 5.9 can be tested thanks to the addition of the specific
    templates.
  - Few parameters are not required anymore by the templates in scenario
    tests; a default value is provided (name of templates, etc).
  - The flavors used in templates are now parameters too.
  - If a flavor name is provided in addition to its specification and
    a flavor with that name exists, it is used and not created again.
  - The dependencies on non-public Tempest interfaces have been
    removed.
upgrade:
  - the name of the variables/parameters used for the name of
    the images in the scenario tests have been changes to follow
    a more consistent pattern.
critical:
  - The Tempest plugin was fixed after the removal of
    the data_processing plugin from the tempest repository.
    Most of the work was in place, only a small change was
    missing.
fixes:
  - The artifacts created during the execution of CLI tests
    are properly cleaned at the end of the tests.
other:
  - The documentation was improved (scenario tests) and
    extended (Tempest plugin).

This is to catch up with the existing changes, let's try to be more
strict about changes with no release notes (starting by me).
