Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "PDF parsing support"
  - PDF parsing support
    
    - add new git submodule pointing to OPNFV Pharos;
    - use Pharos 'generate_config.sh' to parse the PDF using the Fuel
      installer adapter and generate <pod_config.yml> dynamically;
    - build <pod_config.yml> outside current git repo and sync separately
      to prevent sensitive data leak;
    - add <pod1.yaml> PDF sample based on LF-POD2, should be used with
      'ci/deploy.sh -l local -p pod1';
