This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port. - Adds new relay implementation with websocket with single port relaying mechanism - refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection - peer connections are faster since it connects first to relay and then upgrades to P2P - maintains compatibility with old clients by not using the new relay - updates infrastructure scripts with new relay service
