Description

To reproduce:

cumulus-etl init s3://bucket/folder/

without any AWS_PROFILE or anything. You'll get a gross auth traceback. But it should be a nicer, user-friendly error, suggesting to set AWS_PROFILE.

I think it also happens if the wrong --s3-kms-key is provided.

Contributor guide

Research direction
Locate the init command's authentication code, catch the exception, and display a user friendly error message suggesting to set AWS PROFILE.
