UpdatePriceTableRPC

MERGE REQUEST

Overview

This MR introduces the RPC code for the UpdatePriceTable RPC. Note that I have not updated the Changelog, because the RPC is not exposed yet in the host's network code. This will be followed-up with later. This MR merely aims to introduce it and provide a unit test for it.
