Update git submodules

* Update docs/submodules/sfc from branch 'stable/fraser'
  - Improve logging and unify how to read from yaml
    
    vnffgd and vnfd are being parsed in different ways, we should parse them
    in the same way. We could do it directly with safe_load, however, the returned
    object is not easy to read. If we use read() instead, the resturned object is
    easy to read/log. Therefore, this patch combines both options
