Introduce new Ping/Pong message types #1781
Description
Background
As a prerequisite for the echo connection check in #1687, we need to introduce the new Ping/Pong message types and respond to Ping messages with Pong messages.
Once this is released, we can follow-up with a change that starts sending the new Ping messages and expects Pong responses.
User Story
As a developer I want to introduce the Ping/Pong check without requiring a synchronous node upgrade.
Acceptance Criteria
Nodes recognize the new Ping/Pong message format and respond to Ping messages with Pong messages.
