This PR may conflict with #826 (maybe charts/vald/values.yaml).so it is better to wait for it to merge into master.

I think it's okay to merge before merge #826, I'll add same configuration into gateway/{lb, backup, meta}

Thanks for reviewing.
I don't want to make #826 larger more. so please merge #826 first.
