📄 Description

Describe your changes

Add QUIC protocol support for Relay client and server
The Relay client tries to connect with WS and QUIC to Relay in parallel. After the successful connection is maintained, only one of them and the other will be aborted. The system architecture expects all Relay server instances to accept all protocols. The QUIC will listen on the same port number as the WS, just on UDP.

For the test and dev environment, the code generates a fake certificate for the QUIC server and it will automatically be accepted by the Relay client. It is configurable in build time with the -tags=devcert parameter. Keep in mind never to use binary that has been built with these flags in a production system.
