DataSegmentServerAnnouncer (druid-server 29.0.1 API)

All Known Implementing Classes:

CuratorDataSegmentServerAnnouncer, DataSegmentServerAnnouncer.Noop
```
@Deprecated
public interface DataSegmentServerAnnouncer
```
Deprecated.

We are gradually migrating usages of this to DruidNodeAnnouncer. However, it's still required in some cases. As of this writing (2020-12-03) it's required for any process that is serving queryable segments via Curator-based segment discovery. (When using Curator for segment discovery, Brokers look for these announcements as part of discovering what segments are available.)
