Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Remove missing statements in test_odl"
  - Remove missing statements in test_odl

    It mainly removes _fake_url_for() which is useless since get_endpoint()
    is not called for identity.

    Coverage for functest/tests/unit/odl/test_odl.py : 100%
