title: solrcloud replica waiting time configuration
body: <p>I have setup solrcloud cluster with 2 shard 2 replica configuration. But when I start my shard nodes and only one replica node for each shard, the shard leader nodes continuously prints a message: <code>waiting until we see more replicas up,total 3 found 2 timeoutin 175000</code>, the wait time for other replicas to come up here is around 3 min.</p>
  
  <p>My question is how to reduce this wait time, to speedup development ?</p>
