Add appropriate permissions to User groups to list required buckets

[fabdy]

Currently, users added to the DataLakeDebugging group cannot list Buckets, meaning they cannot see Buckets in the S3 console (even though they have access to these). It would be great if they could list these buckets (at least read permissions).

Moreover, users in the DataLakeAthenaUser group cannot list the query results bucket. However users can see historic and saved query results in the Athena console. It might make sense to give them access to the Bucket. We have to align on this.

Tasks:

• give DataLakeDebugging group access to list all buckets
• align whether DataLakeAthenaUser group should be able to list the query results bucket
• if yes: allocate the correct permissions to this group
