Review Comment:
EstimatedBytesToMove is calculated based on the target disk even state with
the configured threshold.
EstTimeLeft is calculated based on EstimatedBytesToMove and configured disk
bandwidth.
Both EstimatedBytes and EstTimeLeft could be non-zero while no containers
can be moved, especially when the configured threshold is too small or disk
capacity is too small.
