Refactor tempest common

It also renames two testcases and updates all docs because tests
run in parallel in case of tempest smoke.

To force one thread as before:
run:
    module: 'functest.opnfv_tests.openstack.tempest.tempest'
    class: 'TempestCommon'
    args:
        mode: '^tempest\.(api|scenario).*\[.*\bsmoke\b.*\]$'
        option:
            - '--concurrency=1'
