Description

On cache evict, orchestrator currently closes upstream and all downstream watches for the key that's getting evicted. This could be problematic if there's a lot of downstream connections for the same aggregated key. This will cause a "thundering herd" problem where all downstreams attempt to re-establish a connection with xds-relay. We need to evaluate how to handle this.
