This CL should be a no-op.
Provide better access to the service ID during bandwidth upgrade handling. Notably, 1) have the endpoint channel store its associated service ID, and 2) send the service ID on a connect/disconnect.
The service ID identifies the application, for example, "NearbySharing". In future CLs, we will use the service IDs to better handle bandwidth-upgrade bookkeeping when multiple services are running simultaneously. Specifically, we will better handle reverting a bandwidth-upgrade medium without interfering with other services.
