Add external-secret.io support to existing EKS clusters

[patrick-black-oddball]

We need the ability to use the external-secrets.io apiversion for parameter store key values. As a result, the extern-secrets.io CRDs need to be added and configured in the existing dev, sandbox, staging and production EKS clusters.

the NEXT EKS clusters use the following code:

• https://github.com/department-of-veterans-affairs/vsp-platform-infrastructure/blob/main/terraform/modules/platform-distro/helm_external-secrets.tf
• https://github.com/department-of-veterans-affairs/vsp-platform-infrastructure/blob/main/terraform/modules/platform-distro/helm_values/helm_external-secrets.yaml

Tasks

• Add CRDs for external secrets
• Configure external secrets

Acceptance Criteria

• An external secret using the external-secrets.io apiVersion successful pulls from the parameter store
