feat: S3 compatibility

[mjdupont12]

set s3 config for drop-box
Works with the dropbox pr "s3 support" => bento-platform/bento_drop_box_service#63

Need to add some documentation.

But if you want to test =>
If s3 params are set, drop-box will use minio/s3.
if not, drop-box will use the filesystem.

The S3 params to set are =>
BENTO_DROP_BOX_S3_ENDPOINT=''
BENTO_DROP_BOX_S3_BUCKET=''
BENTO_DROP_BOX_S3_ACCESS_KEY=''
BENTO_DROP_BOX_S3_SECRET_KEY=''

Looks good! Just missing docs now.
I think we could have a general docs/object_storage.md document that covers how to configure Bento's services for S3 storage backends. Then we can link to this document from the other docs sections.

Started work to make WES work with Drop-Box and DRS over the network only for S3 compatibility. Updated the WES version to use the PR.

Hacky solution at the moment, but it works with Katsu workflows when Drop-Box is using S3.
Does not work with Gohan yet, as the Gohan service also relies on a volume mount to read DRS files (working on that next).

NOTE: For the WES PR to work with S3 drop-box, you need to add the view:drop_box grant to the WES client in authz. This allows WES to download files from drop-box
