Update git submodules

* Update docs/submodules/parser from branch 'master'
  - change some doc file names
    
    upstream rst files kept in the project subdirectory which not meet the
    requirement of OPNFV(in docs/).
    
    issues in
    https://build.opnfv.org/ci/job/docs-verify-rtd-master/1590/console may be
    caused by parser project
