rbd: create pool_id device attribute
Add an entry under /sys/bus/rbd/devices/<N>/ named "pool_id" that provides the id for the pool the rbd image is assocatied with. This is in addition to the pool name already provided. Rename the "poolid" field in struct rbd_device to be "pool_id". Update the documentation to reflect the addition of this new entry.
