Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "[virtual] Set vnc address to local one"
  - [virtual] Set vnc address to local one

    System reclass model assigns vnc address to control_address variable
    which is used for controller node reference, so change it to local
    address of the current compute node.
