Kafka indexing service supports Incremental handoff since 0.12.0 (#4815) and LegacyKafkaIndexTaskRunner was deprecated in 0.13.0.

After this PR, rolling update from a version < 0.12.0 is not supported.

The patch LGTM and I think it's been long enough that it makes sense to remove the old code. Could you please write up a draft of what should go into the release notes? Something about what to do if you're updating from a version before 0.12. Maybe you need to shut down your kafka supervisors first.

@gianm thanks for reminding me. I think I have to do some tests before adding the draft for release notes. I'm especially not sure about what happens if a task which was running with an old version is restored as a new version. I think it should just work as expected with the new version, but will try to make sure.
