* frame/authority-discovery: Have authorities() return both current and next Authority address lookups on the DHT happen periodically (every 10 mintues) and are rather slow (~10 seconds). In order to smooth the transition period between two sessions, have the runtime module return both the current as well as the next authority set. Thereby the client authority module will: 1. Publish its addresses one session in advance. 2. Prefetch the addresses of authorities of the next session in advance. * frame/authority-discovery: Deduplicate authority ids * frame/authority-discovery: Don't dedup on_genesis authorities * frame/authority-discovery: Remove mut and sort on comparison in tests * frame/authority-discovery: Use BTreeSet for deduplication
