 - Use [ServerName as the authority](https://github.com/etcd-io/etcd/pull/11574) after bumping to grpc v1.26.0. Remove workaround in [#11184](https://github.com/etcd-io/etcd/pull/11184).
 - Fix [`"hasleader"` metadata embedding](https://github.com/etcd-io/etcd/pull/11687).
   - Previously, `clientv3.WithRequireLeader(ctx)` was overwriting existing context keys.
