Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "ci/deploy.sh: Allow non-root deploys"
  - ci/deploy.sh: Allow non-root deploys

    Currently, deploying Fuel@OPNFV requires the `ci/deploy.sh` to be ran
    as root user, for:
    - hypervisor access (virsh);
    - installing prerequisite packages;

    We can support non-root deploys if we relax above restriction into:
    - current user should have hypervisor access beforehand
      (new check added);
    - current user has passwordless sudo rights, for installing packages;

    Later, we should move the package installation out of the deploy
    script (`ci/deploy.sh`), making the whole deploy possible without
    sudo, only hypervisor access.

    After this change, the old way (sudo ci/deploy.sh) should work just
    like it used to before, so no regression/behavior change should be
    introduced with this.
