Pinning add-on versions in Terraform

[ImIOImI]

From the examples and documentation provided, it isn't clear how to use terraform to pin add-ons to a particular version. I find this is really important when I want to test changes in lower environments before rolling them out to higher ones.

Thanks for the PR @ImIOImI

Currently is done in the application sets yaml, and is not very intuitive.

We are working on a helm chart for the addons, and the values for this chart will be able to control the versions of the addons at different levels like specific cluster, specific environments (dev, staging, prod),

Early POC in the works today in this repository branch

• Here is the chart https://github.com/aws-samples/fleet-management-on-amazon-eks-workshop/tree/riv24/gitops/addons/charts/gitops-bridge
• This is an example values for specific cluster before you make the change in higher environments https://github.com/aws-samples/fleet-management-on-amazon-eks-workshop/blob/riv24/gitops/addons/clusters/fleet-spoke-staging/addons/gitops-bridge/values.yaml
