Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Add neutron and glance policy.json for patrole

    It only runs tests about neutron and glance because their policy.json
    can be still downloaded. Installers could override them via docker
    volumes if needed.

    Several tests about provider networks are currently excluded because
    GRE is selected.
