> For shards which have 1 replica ( leader ) we know it doesn't need to recover
> from anyone. We should short-circuit the recovery process in this case.
> The motivation for this being that we will generate less state events and be
> able to mark these replicas as active again without it needing to go into
> 'recovering' state.
> We already short circuit when you set {{-Dsolrcloud.skip.autorecovery=true}}
> but that sys prop was meant for tests only. Extending this to make sure the
> code short-circuits when the core knows its the only replica in the shard is
> the motivation of the Jira.
