Update git submodules

* Update docs/submodules/functest from branch 'stable/euphrates'
  - Define thirdparty-requirements.txt for functest-parser
    
    As Parser python packages has been renamed, they can be defined in
    upper-constraints.txt. No conflict can occur between them and the
    official OpenStack packages.
    
    The Parser testcase still requires a dedicated container to avoid
    conflicts in namespaces.
    
    Conflicts:
        docker/parser/Dockerfile
        upper-constraints.txt
