    Support Ansible max_fail_percentage · af6e1ca4
    Mark Goddard authored 
    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
