@jack-berg I think the changes suggested by errorprone here are fine. I'm not in love with the conversion to a builder for the OkHttpGrpcSender, but I also think it's a fine change, since it's not in the hot path of anything. Feel free to veto any changes here you think are not good ones.

Suggested change

	public OkHttpGrpcSender<T> createOkHttpGrpcSender() {
	public OkHttpGrpcSender<T> build() {

LGTM, but I did mention that I think the action method on the builder should be spelled build() but otherwise seems good.
