support affinity in helm chart

[yalattas]

Summary

Its much simpler to use affinity to schedule pod to a dedicate NodePool, current chart doesn't have affinity with label

Use cases

For provisioning pod to a specific NodePool. It will allow to use podAntiAffinity as well to distribute pods across AZs for High-Availability

Proposed solution

add Affinity in deployment inside helm chart

Is there a workaround to accomplish this today?

I guess NodeSelector. Havn'e test it yet

Hi @yalattas,

This has been brought up previously (1Password/connect-helm-charts#133). As mentioned, we've logged this internally to implement and are currently reviewing a PR to potentially solve this!
