Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - [vcp] Catch 'no response' of salt minion as well

    Salt minion could return 'no response' and cause an
    unconfigured state of the vcp node(s), so catch this output after linux
    state as well. Also clean up excess route on proxy nodes.
