Code Issues Proposed changes

Support Ansible max_fail_percentage

Browse Source 
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.

Max failure percentage
----------------------
It is possible to specify a `maximum failure percentage
<https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_error_handling.html#setting-a-maximum-failure-percentage>`__
using ``kolla_max_fail_percentage``. By default this is undefined, which is
equivalent to a value of 100, meaning that Ansible will continue execution
until all hosts have failed or completed. For example:
.. code-block:: yaml
kolla_max_fail_percentage: 50
A max fail percentage may be set for specific services using
``<service>_max_fail_percentage``. For example:
.. code-block:: yaml
kolla_max_fail_percentage: 50
nova_max_fail_percentage: 25

Adds support for setting the max fail percentage for Ansible plays via
``kolla_max_fail_percentage``. It can also be set on a per-service basis,
e.g. ``nova_max_fail_percentage``.
