Update git submodules

* Update docs/submodules/osa.git from branch 'master'
  to 0131effd6aec0e8f2c6fd1b9be485b68b47fc58a
  - Explicitly mention onap-security ML in our process

    onap-security mailing list is never mentioned in the vulnerability
    management. Let's fix this by adding this as a legitimate option of
    reporting security vulnerabilities
