    Support Ansible max_fail_percentage

    This allows us to continue execution until a certain proportion of hosts
    to fail. This can be useful at scale, where failures are common, and
    restarting a deployment is time-consuming.

    The default max failure percentage is 100, keeping the default
    behaviour. A global max failure percentage may be set via
    kolla_max_fail_percentage, and individual services may define a max
    failure percentage via <service>_max_fail_percentage.

    Note that all hosts in the inventory must be reachable for fact
    gathering, even those not included in a --limit.
