* Update docs/submodules/aaf/certservice.git from branch 'master'
  to 2edef3c2aaafba49439e20aa13eb647c67c781d5
  - Added validation of configuration

    Fields are being validated right after reading servers details from JSON (when application starts).
    Created own annotation to validate server URL with proper requirements.
    When invalid details are given application closes.
