Migrate package movement to use new API.

Browse Source 
We now kick off the move immediately, and pass along the "ID" of the
move in progress.  This allows the progress activity to be completely
destroyed and recreated without kicking off a second conflicting move
operation.

Also uses new cleaner movement API that accepts direct VolumeInfo.
