Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "Identify jump host bridges based on IDF / PDF nets"
  - Identify jump host bridges based on IDF / PDF nets

    - minor refactor of runtime templates parsing to allow var expansion;
    - parse <pod_config.yml> into shell vars, match dynamically networks
      from PDF to IP addresses on bridges of current jumphost;
    - keep old '-B' parameter in <ci/deploy.sh>, use it for providing
      fallback values in case there's no bridge name specified via IDF
      and no IP on the jumphost for one or more of the PDF networks;
    - re-enable dry-run to ease testing of the above;
    - add sample 'idf-pod1.yaml' to <mcp/config/labs/local>;

    The new behavior will try to determine the jump host bridge names:
    1. Based on IDF mapping, if available
    2. Based on PDF network matching with IP addrs on jumphost;
    3. Fallback to values passed via '-B';
    4. Fallback to default values hardcoded in the deploy script;

    Later, we will drop MaaS network env vars in favor of PDF vars,
    once the PDF template is generating them.
