Update git submodules

Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Stop hardcoding results suffix in push_to_db"
  - Stop hardcoding results suffix in push_to_db

    Adding results in url is useless as it is defined in results
    section in config_functest.yaml.

    It allows defining the full name in case of dumping to file (see
    decorator.py). The commented local file is the value required by
    dovetail.
