Review Comment:
it'd be nice to add something like:
```
public <RequestT, ResponseT> ClientCall<RequestT, ResponseT>
newCall(MethodDescriptor<RequestT, ResponseT> descriptor) {
return getChannel().newCall(descriptor, getCallOptions());
}
```
to the stub so we could just do `stub.newCall(descriptor)`, but it looks
like that class is auto-generated so I'm not sure where to add it.
