Wire Eureka packet handler to Msg Server

[AdityaSripal]

All of the packet handler functions are in the packet server function.

We need to now wire this into the message server that can handle both the Classic and Eureka message processing. We will switch based on the Protocol Version specified in the packet.

We will retrieve the callback using our side's portID and use the version specified in the packet

Will take care of #7049 (comment) in this as a wiring test above all.
