Additional Notes

[csantanapr]

We are not accepting more generic helm charts that do not require any aws metadata, we added a variable helm_releases you can pass as many helm charts you want as a map take a look at the example here https://github.com/aws-ia/terraform-aws-eks-blueprints-addons/blob/main/tests/complete/main.tf#L189C3-L219

This allows the user to specify an infinity number of helm charts, or they can use the normal terraform helm provider them selfs outside the eks blueprints addons module. the module doesn't add any value to these charts
