> solrj CloudSolrClient: add directUpdatesToLeadersOnly support
> (Marvin Justice, Christine Poerschke)
> Proposed change:
> * Addition of a {{directUpdatesToLeadersOnly}} flag to allow clients to 
> request that direct updates be sent to the shard leaders and only to the 
> shard leaders.
> Motivation:
> * In a scenario where there is temporarily no shard leader the update request 
> will 'fail fast' allowing the client to handle retry logic.
> Related tickets:
> * SOLR-6312 concerns the ((currently) no longer used) {{updatesToLeaders}} 
> flag. The updatesToLeaders logic however appears to be slightly different 
> from the proposed directUpdatesToLeadersOnly logic: {{updatesToLeaders}} 
> indicates that sending to leaders is preferred but not mandatory whereas 
> {{directUpdatesToLeadersOnly}} mandates sending to leaders only.
