In v0.6.0, the heartbeat is sent over gRPC which is HTTP/2 over TCP.

We don't need a connection to send heartbeat. Even the response is not necessary. It is just leader sending heartbeat to followers periodically (like 100ms).

If we can send the heartbeat over UDP, there is no connection and it is ideal.
