Introduce new extended attribute: node-uuid
Request for trusted.glusterfs.node-uuid returns pathinfo like string but containing the UUID of glusterd instead of the backend path for the requested file. This info is benificial for tasks like parallel rebalance that will make use of the UUID for data locality.
