1. Need a docs/cli/file.rst update
2. Merge the file/block manager commands into the storage_utils manager
3. I'd like a little more documented about what actually happens when you run these commands. If there is documentation being created that explains all that on cloud.ibm.com or something linking to it in the docs/cli area should be fine.
4. Since the refreshDependentDuplicate command isn't out yet, this will likely be on-hold until it is public.
5. Unit tests.

I've refactored the file/block managers, which will likely conflict with your changes.

When you get a chance, you might want to pull in the changes from #1235 (or just wait until its merged to master).

The practical effect is that you'll just put your file/block manager new functions into the new storage manager since they are the exact same between file and block.
