Add loadConfig S3 based on AWS_PROFILE ~/.aws/credentials

[alban-stourbe-wmx]

Proposed changes

To retrieve a S3 bucket based on a loacConfid, i have added a feature allowing to use AWS_PROFILE from ~/.aws/credentials file.

The aim is to be able to use the profile option from aws cli like
aws s3 ls --profile my-profile
