Breaking Changes

Deprecate v2 storage backend.
- v2 API is still supported via v2 emulation.
clientv3.Client.KeepAlive(ctx context.Context, id LeaseID) (<-chan *LeaseKeepAliveResponse, error) is now clientv4.Client.KeepAlive(ctx context.Context, id LeaseID) <-chan *LeaseKeepAliveResponse.
- Similar to Watch, KeepAlive does not return errors.
- If there's an unknown server error, kill all open channels and create a new stream on the next KeepAlive call.
