GH-79 Copy and delete performance

[bstopp]

Description

Copy & Delete now return a specific status code based on resulting state:

• 204 if the operation is complete
• 206 if there is more to process.

Copy Operation will return a list of remaining Keys that need to be updated. If present, will not query system again, will just operate on the list. If still more remain after sub-process limit is reached, repeat the call via client.

Delete operation can simply be called again and again until a 204 response is returned.
