Hi folks

I would like to make the PRC versioning policy clear.
Which policy we choose?

For update version.

(Policy A)  Update version if the structure of dict on existing API is
(Policy B)  Update version if the new API is added.

For backward compatibility.
(Policy X)  We have RPC Classes for each version, so let's
it configurable from conf.
(Policy Y) If version N+1 is compatible with N, we simply have a
version N+1 class here.
