Review Comment:
I don't like this change (thus don't like
leaderLogicWithVersionIntegrityCheck). If there is some race condition causing
the client to route to us (a new sub-shard) before we know that we are ready to
accept it, I'd rather not pretend we are ready in any way. Maybe throw an
exception like INVALID_STATE that should cause CloudSolrClient to retry. Our
state will update eventually.
