feat: remove flyway as init container and deploy it as a separate task

[mishraomp]

currently. flyway is deployed as init container. it works but impacts auto scaling as it takes around a minute(image pulling, scheduling et..) for flyway container to be provisioned and complete.

this change would remove flyway from init container and will only execute during rollout.

this will make sure that when autoscaler kicks in it is only executing node api container and ready to server incoming traffic within 10 to 20 seconds.

successful deployment: https://github.com/bcgov/quickstart-aws-containers/actions/runs/12437101568/job/34726315097
and flyway task is executed successfully.

here is the sample that it takes around a minute

I like this SO MUCH better! Transparency. Great job. :)

I think we should port it back to quickstart openshift, and run flyway as a job during rollout to avoid init container, and api rollout will depend on flyway rollout, thoughts?

[DerekRoberts]

Agreed. The challenge is how to structure that for k8s where init pattern, which I hate, is the recommended path. Deployments are generally supposed to happen simultaneously.

[DerekRoberts]

Well, should. We're going to deviate!
