+# You can specify the number of nodes to upgrade at once. We do not currently
+# attempt to verify that you have capacity to drain this many nodes at once

+# upgrade. If it's not possible to drain the requested nodes the upgrade will
+# stall indefinitely until the drain is successful.

+# If you're upgrading more than one node at a time you can specify the maximum
+# percentage of failure within the batch before the upgrade is aborted. Any
+# nodes that do fail are ignored for the rest of the playbook run and you should
