Add option to distcp to preserve file path structure of source files at the destination

When copying files using distcp with globbed source files, all the matched files in the glob are copied in a single flat directory. This causes problems when the file structure at the source is important. It also is an issue when there are two files matched in the glob with the same name because it causes a duplicate file error at the target. I'd like to have an option to preserve the file structure of the source files when globbing inputs.
