Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - mcp: lib.sh: virt-install --noautoconsole

    When X server is available, virt-install tries opening virt-viewer
    automatically (for each newly created VM), which blocks the
    deployment until the user closes the virt-viewer window.

    Without X, virt-install just throws a warning and moves on.

    Fix both of the above by passing the "--noautoconsole" argument to
    virt-install.
