   **Is your feature request related to a problem? Please describe.**
   A compaction reduces many files to one. During this process the input files 
are read, an output file is created (maybe on a different volume), and the 
tablet metadata is updated appropriately. There is a case where a user may want 
to move files from one volume to another, and the compaction mechanism is the 
only way to do it. However, performing a compaction can be resource intensive 
depending on the iterators involved.
   
   **Describe the solution you'd like**
   Create a new major compaction-like task that performs the same overall 
process, but instead of reducing the input files, just copy the files input 
files to output files. Instead of being many to one operation, this would be a 
one to one operation. As an optimization, the copy could be done below the 
RFile level to just copy the underlying file from the Volume.
