[doc] Refactored existing tempest API tests

Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/watcher" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Refactored existing tempest API tests

    We must set up Tempest for Watcher
    (http://docs.openstack.org/developer/tempest/configuration.html)
    to run integration tests inside devstack environment.

    This patchset is a refactoring of the stale Tempest tests to now
    use the latest Tempest coding standards (like using plugins and
    credentials factory).

    This commit will have an effect on the doc as we need to integrate
    Tempest in the Watcher documentation.

    They are now part of the main documentation.
