Review comment:
some test to check that EmptySegmentPruner is added as expected if 1.
already in table config 2. because streaming table with isEmptySegment?

Review comment:
this is leaking immensely specific information into the broker about
Kinesis and the behavior of empty segments. Plus, adding kinesis plugin
dependency in pinot-broker is not the best..
How about one of these options:
1. Add validations to TableConfigUtils.validate, to check that a kinesis
stream table has this pruner added (or if there's any logic in that path which
decorates the table config)
2. Move this mthod `isKinesisEnabled` to `TableConfigUtils` ad rename it as
`needsEmptySegmentPruner`. Part of that, check if routingTypes already has
EmptySegmentPruner, if not check if kinesis. Possibly even add
"needsEmptySegmetPruner" to StreamConfig
