23 RPC definition fields:
26 - L{SINGLE} for single-node calls, L{MULTI} for multi-node
27 - Name resolver option(s), can be callable receiving all arguments in a tuple
28 - Timeout (e.g. L{constants.RPC_TMO_NORMAL}), or callback receiving all
29 arguments in a tuple to calculate timeout
30 - List of arguments as tuples
33 - Argument kind used for encoding/decoding
34 - Description for docstring (can be C{None})
36 - Custom body encoder (e.g. for preparing per-node bodies)
37 - Return value wrapper (e.g. for deserializing into L{objects}-based objects)
38 - Short call description for docstring
