Update git submodules

Update git submodules

* Update docs/submodules/compass4nfv from branch 'master'
  - Merge "opera adapter fix2"
  - opera adapter fix2

    * opera_adapter need sshpass which may cause deploy
    fail
    * compass log redirection is the last command which
    always return 0 and thus cover deploy error

    1. add installation of sshpass in prepare.sh
    2. echo a string at the end of deploy/launch.sh into
    log file to judge if deployment is complete
    3. fix typing error in util/check_valid.py
