Jiri Stransky 021d1b1efb Stop upgrade if a task on one node fails
When we were upgrading multiple nodes at the same time,
e.g. controllers, and a taks on one of the nodes failed, the other
nodes would keep upgrading. This is undersirable and can be fixed by
adding any_errors_fatal to the Ansible plays.
