Can we roll this into HDFS-7173?  It's a pretty small change and I have trouble seeing what
it's doing without HDFS-7173.

> Hot swapping data volumes might fail. The user should be able to fix the failed volumes
and disks, then ask the {{DataNode}} to retry the previously failed volumes. 
> To attempt to reload the failed volume again on the same directory, this failed directory
must not be presented in the {{Configuration}} object that {{DataNode has}}. Therefore, it
should only put successfully loaded volumes into the {{Configuration}} object.
