Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - [j2 parsing] Adopt new generate_config features
    
    - bump Pharos git submodule for j2 'do' extension + batch mode;
    - adopt j2 'do' in our templates;
    - use int filter for 'native' vlan check;
    - lib.sh: adopt `-i` to remove `ln` hack for net_map.j2;
    - lib.sh: adopt `-b` to speedup template parsing;
    
    NOTE: Bumping Pharos will also bring in the latest changes in
    pod_config.yml.j2, which include massive IP shifts and updates.
