Reliable delivery in Typed, #20984

Browse source 
Different approach than in classic AtLeastOnceDelivery because I would like:
* support flow control, with a work pulling approach
* be possible to use with or without persistence (without it may loose
  messages if producer node crashes)
* detect lost messages on the consumer side and let that drive resends,
  instead of aggressively resending from producer side
* deliver messages in order and deduplicate resent messages
* have an efficient protocol for acknowledgments over the network (not ack each message),
  but still have a simple one-by-one protocol for the end user

* support 3 use cases (building blocks)
  * point-to-point
  * work pulling
  * sharding
* optional durable queue, with one event sourced implementation
* protobuf serialization
* ApiMayChange
* reference docs and examples
* api docs
* doc example code missing so far
