  - xci: Make it possible to skip deployment and healthcheck

    This change adds possibility for patch submitters to skip the full
    xci-verify if the change doesn't impact the deployment.

    Since the patch will be reviewed by others, reviewers can always
    ask the submitter to run it through full xci-verify by changing
    the topic and posting reverify or recheck as comment to gerrit
    change.

    The keyword to put in topic branch is skip-verify.
