Update git submodules

* Update docs/submodules/vid.git from branch 'dublin'
  to 71e820e32bd4f32aff4026fc55c6bb1f5891a0c2
  - Find the first selected scale-out vfModule (fix)

    Issue in original code is that it used callback function(key, item), but
    function(item) or function(item, key) is the correct parameters order.

    See https://lodash.com/docs/4.17.11#find
