Update git submodules

* Update docs/submodules/stor4nfv from branch 'master'
  - Merge "manage local patches"
  - manage local patches
    
    We could not put the source code of ceph or other projects due to
    different license, and so we have to only manage those changes locally.
    This patch provides one way to apply local patches into source code
    from public repo.
    
    We can use the '.rc' file in every project to configure the branch, repo
    and list all local patches which need to be applies into original branch.
    And then use 'do_patch.sh' script to apply them one by one, e.g.
      $ src/do_patch.sh src/ceph/ceph.rc
