Avoid serializing object-based payload into PacketByteBuf on the main thread (#3407)

Browse source 
* channeled network addon refactor

* checkstyle

* fix junit tests

* convert TypedPayload <-> UntypedPayload if necessary

* assert payload size

* add vm arg to force serialization

* change log level to info and make it single line

(cherry picked from commit 6225d43a70)
