Mark Goddard 6c54ce4d3b Introduce max fail percentage to playbooks
This allows us to continue execution until a certain proportion of hosts
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
kayobe_max_fail_percentage, and individual playbooks may define a max
failure percentage via <playbook>_max_fail_percentage.
