Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "xci: Set options in run-functest.sh"
  - xci: Set options in run-functest.sh

    Functest healthcheck job actually fails but due to not setting
    options properly in run-functest.sh, we failed to notice this.

    Please note that this patch will enable changes to be blocked
    since creation of external network and associated subnet fail,
    due to an upstream issue. This causes functest healthcheck to
    fail which in turn results in Verified-1 on Gerrit.
