> This Jira trys to support rename of directory across namespaces using
> fedbalance framework.
> We can do the router federation rename when:
> # Both the src and dst has only one remote location.
> # The src and dst remote locations are at different namespaces.
> # The src is a directory.(Fedbalance depends on snapshot).
> # The dst doesn't exist.
> We can implement router federation rename of file in a new task so the patch
> won't be too big to review.
