Use taskflow to obtain reliable running and resumption of nova<->glance snapshot task set

Registered by Joshua Harlow on 2013-11-25

Taskflow was built to help track and resume and reliably run workflows. Its usage in ensuring the conductor reliably uploads a snapshot to glance seems natural. Usage of taskflow reduces the code needed to track state, monitor progress and get involved in the inner details of the state transitions required to resume or revert a workflow if said workflow is interrupted via some external (or internal) mechanism.
