    Add --ansible-opts for upgrade-non-controller.sh O->P upgrade

    This allows the operator to pass extra options to the invocation
    of ansible-playbook. In particular this can be used to skip the
    validation tasks using the --skip-tags option, for example:
    --ansible-opts "--skip-tags validation -vvv" to skip validation
    and enable verbose logging
