> In the regionserver, when the rpc receives a call, the call is described using protobufs.
 Before we make the server-side invocation, we do a transform on the pb param objects to make
a native pojo -- e.g. from a pb Puts into an hbase o.a.h.h.client.Put -- and only then do
we make the call against the server.
> On the way out, similar, before putting the result on the wire, we will do a convertion
from o.a.h.h.client.Result into pb Result.
> This issue is about our first INVESTIGATING if it is possible to do away w/ this marshalling/unmarshalling
serverside especially given the pb objects themselves are rich in accessor and getters, etc.
 If it is possible to do w/ pbs alone serverside, then we should go ahead and rip out all
the serverside convertions.
