Code Review

This pull request introduces a Flask-based UI example for Apigee API generation and deployment, along with its Docker configuration and static assets. Feedback highlights a critical command injection vulnerability in app.py due to unsafe shell execution of user-controlled input. Additionally, several files contain redundant or entirely commented-out code—including active_app_backup.py, app2.py, and sections within app.py and the Dockerfile—which should be removed to maintain code cleanliness.

ALM isn't in Snippet-Bot's official product list yet, but alm_ui_sample is the correct intended tag for this product snippet.

[QMeng]

Can a maintainer please add the snippet-bot:no-prefix-req label? ALM isn't registered as a product prefix yet.
