rbd: add volume_id to connection_info in initialize_connection
Most other volume drivers have a 'volume_id' key in the
connection_info['data'] dict returned from initialize_connection, this
adds it to the rbd volume driver.
This is part of a bigger effort to standardize the connection_info dict
so that consumers like Nova can rely on a common set of keys when
processing connection_info.
