Migrate to new S3 Bucket for Example Data

[ckunki]

In the past @ahsimb created an experimental bucket called us-flight-info. Now, after implementing ticket #301, the AI Lab supports creating a new s3 Bucket "Example Data".

The current ticket requests to

• [x] update the URL in the related IBIS notebook: flight_utils.ipynb and
• [x] copy the files from the old bucket to the new one, and
• Finally delete the old bucket:
  • [x] Disable related Cloudfront distribution
  • [x] Delete related Cloudfront distribution
  • [x] Delete Origin Access Control of CF Distribution
  • [x] Empty the bucket, i.e. delete all contained folders and files
  • [x] Delete the bucket

Currently we decided to move the files into a subfolder

• <URL>/ai_lab/flight-info/
• E.g. <URL>/ai_lab/flight-info/US_AIRLINES.csv

This is merged already. @tkilias will remove the S3 bucket when ready.
