Generate and print an S3 pre-signed URL

Can do the same with the following AWS CLI command:

aws s3 presign s3://<bucket>/<key> [--expires-in <secs>]

Will generate a pre-signed URL even when the bucket and object key don't exist!

(you will get a runtime error when requesting the link that the bucket or object doesn't exist)

Uses the Boto library, read here for the list of ways to configure your AWS credentials:
