Add an option to copy files on query deployment

Currently when publishing a query there is an option to copy the meta information, but no option to copy the physical files.  In cloud environments this would probably a useful option.  (The option is available in the base calls, but defaults to false.)

The same should go for the other places which add roxie meta data (queryset copying and package map deployment).

Note: Care should be taken to ensure the files are copied efficiently and in parallel.  Currently the code would copy them on esp, but it may be better to use a load balanced dafilesrv, or directly use the cloud apis where possible.
