Update git submodules
* Update docs/submodules/functest from branch 'master'
- Merge "Define thirdparty-requirements.txt for functest-parser"
- 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.
