Description

My plan is commit SOLR-11702 on the next 7.x release. We have to support both old and the new design so users can do rolling updates.
This makes code base very complex, in 8.0 we do not have to support rolling updates, so this issue is created to remind us to remove all the old LIR implementation in 8.0.
