Part of blueprint versioned-rpc-apis. One side effect of this change was that nova.scheduler.api was removed in favor of nova.scheduler.rpcapi. In this case, the api was just a direct wrapper around rpc usage. For other APIs, I've been following the pattern that the rpcapi module provides the rpc client wrapper, and if any other client-side logic is needed, that's where an api module is used.
