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. Closes-Bug: #1833737 Change-Id: I808474a75c0f0e8b539dc0421374b06cea44be4f
