This change makes the leader elector use a client that internally has a smaller timeout than the renew deadline, which avoids a situation where a single request timing out makes us lose the leader lease.

This change is a follow-up to the one that introduces the usage of the leader-elector with client timeout. That change was breaking because it introduces a new option and always assumed it was set. This change makes us only use that option if its actually set.
