* Update docs/submodules/releng from branch 'master'
  - Remove reverify for opnfv-lint and gate-security

    This is temporary, using reverify does not work in global-jjb
    for for now remove surrounding jobs so that users dont think its working.

    I've been told we can add reverify into global-jjb
    after that is done, I will re-add these.
