* [frame/im-online] remove `external_addresses` from heartbeats
Users should use DHT for discovering new nodes. The reason for adding external addresses was
unstable work of authority discovery (see https://github.com/paritytech/substrate/issues/2719),
which is now stable. Hence we can safely remove `external_addresses`.

current value is somewhat arbitrary and needs to be tweaked depending on
memory usage and network worker sleep stats.

Secure Websocket transport needs unresolved addresses, so we join DNS transport with
yet another instance of Websocket transport.
