Description

The design docs for Xattrs stated that we handle preserve options with copy commands

From doc:
Preserve option of commands like “cp -p” shell command and “distcp -p” should work on XAttrs.
In the case of source fs supports XAttrs but target fs does not support, exception about XAttrs not supported will be thrown.
