> Today the default placement strategy is the same one used since Solr 4.x
> which is to select nodes on a round robin fashion. I propose to make the
> autoscaling policy based replica placement as the default policy for placing
> replicas.
> This is related to SOLR-12648 where even though we have default cluster
> preferences, we don't use them unless a policy is also configured.
