Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "kubespray: Do not grep log text to determine failure"
  - kubespray: Do not grep log text to determine failure

    Pipefail should be sufficient to determine the failure so this
    change gets rid of grepping the logs for failure and unreachable
    to leave the evaluation to bash itself.
