* Update docs/submodules/sfc from branch 'master'
  - Fix "Remove the annoying WARNINGS when using XCI"

    When executing the SFC tests in XCI, we constantly get a whole bunch of
    annoying "InsecureRequestWarning" messages which does not allow to
    follow what is going on in the test.
    This patch filters all those errors leaving the output of the functest
    results clean.
