upgrade clusterstate.json fom 4.10.4 to split state.json in 5.2.1

[Yago Riveiro]

Hi,


How can I upgrade the clusterstate.json to be split by collection?


I read this issue https://issues.apache.org/jira/browse/SOLR-5473.


In theory exists a param “stateFormat” that configured to 2 says to use the 
/collections/collection/cluster.son format.


Where can I configure this?
