On Staging:
1. Build new docker image for feature-flags (`latest` tag)
2. Apply terraform
Repeat on prod right before landing, with `0.1.1` docker tag
WARNING: We have the same image tag for staging and prod.In case of problems, So applying terraform (specifically creating new ECS Deployment) will pull the latest Docker image on staging as well as on prod.revert this and terraform apply again - this will revert deployment back to the existing v0.1
