      Description

      In the case that the leader tablet server is up but "frozen", the client will get a connection negotiation timeout while starting or continuing a scan operation. The code in KuduScanner::Data::OpenTablet() does not allow the scan operation to failover to different tablet server even if operation timeout setting would allow to wait for a new leader to be elected.

      So, the client gets a failure even if there has been a leader re-election within the client-provided deadline.
