Add minio module for S3-compatible object storage

Label Studio _really_ prefers using a direct object storage model. Can't
say I blame them, it makes sense given they are running Python.

I had to bump Authentik to not use its default port so that minio could
use its own default port. That seemed safest given that Authentik is
always proxied but minio/S3 may _not_ be. I'm just not sure.
