1. Send an ErrWatchStopped to the caller only once. - Currently ErrWatchStopped gets sent to the caller multiple times causing a resubscribing watch to fail as well. 2. Use context with leader requirement for Watch API. - By default the etcd watchers will hang in case of a network partition and they are connected to the minority. - As mentioned here - etcd-io/etcd#7247 (comment) setting the leader requirement for watchers allows them to switch to the majority partition.
