Consider adding AbstractStub.withCallOptions()

[ejona86]

It would fully overwrite the current CallOptions. That could be considered "bad" because you don't know what you are overwriting, but it seems there are fine times to do so. Maybe it would be better to have a new generated method newStub(channel, callOptions) instead?

Totally agree. I was surprised not to see the newStub function that would accept CallOptions

I came looking for this functionality, too. I want to be able pass a CallOptions to the generated newBlockingStub functions.
