* Update docs/submodules/releng from branch 'master'
  - Disable SFC verify job in fraser branch
    
    We would like to disable the SFC verify job for fraser branch
    because jenkins give us -1 on new patches on stable fraser branch
    because of the lack of tox on that branch.
    
    We are not going to submit any new patches on the SFC fraser branch from
    now on except from one [0]. So we can disable the fraser job as an easy
    fix to the -1 jenkins-ci problem in gerrit.
