> Currently IMRU Task State allows the client to save the task state in memory and restore
from it in recovery. It doesn't support the scenario where master evalautor fails. In order
to support fault tolerant for master evaluator, we need to provide a way for client to persistent
the task state in a storage, and restore from storage in recovery.
