Description

Leases/reservations on searcher instances would give us the ability to use the same searcher across phases of a distributed search, or for clients to send multiple requests and have them hit a consistent/unchanging view of the index. The latter requires something extra to ensure that the load balancer contacts the same replicas as before.
