feat: make cosmo usable with aws s3

[AndreasZeissner]

Motivation and Context

This enables virtual-host based s3 paths to be used for the S3_STORAGE_URL in the controlplane and the cdn.
When using aws ensure to set the S3_REGION e.g.:

S3_REGION: us-east-1
S3_STORAGE_URL: https://cosmo-bucket.s3.amazonaws.com

By default, the username and password is taken from the url itself.

e.g.: https://username:password@minio:9000/cosmo

This is done for backwards compatibility and can be used by default.

When needed it's possible to pass: S3_ACCESS_KEY_ID and S3_SECRET_ACCESS_KEY for credentials management.
The S3_ENDPOINT is usually built out of the url.orgin but can be passed if needed.
