Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Add all tempest smoke test cases into debug test suite
    
    Add all tempest smoke test cases into debug test suite.
    Then these test cases can be run by Dovetail on CI.
    The results of CI will help to choose sub test cases from tempest smoke.
    
    Here use tempest_custom to run all tempest smoke test cases because it can
    support to run a custom defined sub test cases list.
    for Functest tempest_smoke_serial, it always runs whole tempest smoke
    test cases and can't be a subset.
