Summary: solrj CloudSolrClient: add directUpdatesToLeadersOnly
support
Key: SOLR-9090

Issue Type: New Feature

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.
