- Azure Devops Pipelines which:
    - Build new container images when triggered by CI
    - Deploy/update full AWS infrastructure, when new container images are created or the IaC is updated
    - Delete the full AWS infrastructure at 2000 UTC every day. Excepting the AWS Secrets, which must be retained for at least 7 days - preventing easy deletion + recreation
    - Uses the Azure Key Vault to securely store secrets for the pipeline runs

Changed:
  - Base container for web and cron, changed to python-slim. Speeds up CI pipeline by avoiding alpine limitation, where some pip packages must be compiled
  - Moved some magic number values from cfn templates into template parameters
  - Changed gunicorn server debug from True to False
