> If I create a collection with autoAddReplicas=true in Solr 7.x a AutoAddReplicasPlanAction
get's created with a waitFor=30 seconds
> The default should be increased as a JVM which is down for more than 30seconds can cause
the framework to add a new replica on another node
> With HDFS this was a cheap operation as it only involved create a core and pointing it
to the same index directory. 
> But for non shared file systems, this is a very expensive operation and can potentially
move large indexes around so maybe we should have a higher default
