Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "[nosdn-noha] Meet EPA testcases requirements (NUMA)"
  - [nosdn-noha] Meet EPA testcases requirements (NUMA)

    Install in a local directory a newer version of virt-manager
    to workaround obsolete Ubuntu versions lacking --cpu cellN.* support.

    This change only affects CPU cfg of virtual compute nodes in
    nosdn-nofeature-noha scenarios with:
    - set default cpu_topology to dual socket (2 cores, 2 sockets,
      2 threads);
    - bump default RAM to 16GB;
    - define 2 NUMA cells, each with half the resources;

    To keep the old behavior available (single socket), a new deploy
    argument has been added (`-m`). The RAM change is not configurable
    via deploy args.

    NOTE: The CPU topology for virtual nodes should later be read from
    PDF instead of hardcoding it on a per-scenario basis in the installer.

    NOTE: Default 'ram' unit is MiB, while cellN.memory default unit is
    'KiB'.
