This patch drops several uses of the RpcCallback compatibility class. All of these were trivial and straight forward conversions so I batched them up. There are still several other uses of RpcCallback, but the conversions are were not necessarily trivial, and may be broken in one way or another, so I wanted to address them separately. In particular, the use of mixin classes means that there could be cases where the version declaration is being stepped on, so they need to be investigated more closely. Part of blueprint drop-rpc-compat. Change-Id: I0977aee863d4fcc6a14a025215c6e41fe38a87f0
