#242 - Remove Airflow authentication

[nikki-t]

Purpose

Remove Airflow authentication so the user only needs to authenticate with Cognito when navigating to the top-level proxy URL.

Proposed Changes

• [REMOVED] Removed Airflow authentication

Issues

• [New Feature] Experiment with removing the Airflow authentication altogether #242 - Experiment with removing the Airflow authentication altogether

Testing

• Deployed modifications on existing Airflow installation and confirmed no authentication was required. No login screen was presented when navigating to the UI and landed on the Airflow dashboard.
• Destroyed Airflow deployment and re-deployed. Confirmed that no authentication is required for a new deployment.
• The option to log in is still present in the upper, right of the UI and if the user clicks on the "Log In" button they can log in with the airflow_webserver_username and airflow_webserver_password defined in the deployment's .tfvars file.

I tested that the system behaves exactly as described. We will keep the changes in this branch without merging pending further testing with the CS proxies and discussion with the Unity team.
