This change removes the healthcheck endpoints from the frontend and frontend_identity docker images so these can now reach the app containers which serve there own healthchecks.
We also update the publish scripts to be a bit neater and use functions.
[x] Update the consuming services reference to the build images, for the content service and identity (frontend), (content uses default variables for tag, identity overrides these).
[x] Optionally: remove the default references to the old container images from the terraform-aws-ecs-service
[x] Update the staging environment for the content and identity services to use the new container image after ensuring the services serve healthcheck endpoints, needs:
Healthchecks that really test if the application is running protect us from broken deployments going out, and ensure the application container is really serving requests when marked as healthy.
