Update git submodules

* Update docs/submodules/fuel from branch 'stable/euphrates'
  - Merge "states: maas: Add 30s delay in re-deploy attempt" into stable/euphrates
  - states: maas: Add 30s delay in re-deploy attempt

    Occasionaly, MaaS fails to provision/deploy some nodes, in which
    case we try marking them as broken, then fixed (to put them again
    in 'ready' state); before re-attempting the MaaS deploy operation.
    However, this leads to 'Error: Internal server error' when deploy
    function is called right after transitioning the node to 'ready'
    state.

    Add a delay of 30 seconds before re-attempting the failed operation.
