This reverts commit 42ca240e81 which
was a breaking change in a library consumed by other OpenStack
projects with no deprecation or backwards compatibility
considerations. It was able to merge because openstack/taskflow is
apparently not yet part of the integrated gate via the proposed
I202f4809afd689155e2cc4a00fc704fd772a0e92 change.
