User request:

Can we open a ticket to add a recursive flag? It's not too hard to go through the S3 gateway but it requires setting up another profile for the AWS credentials, and people will have to install the AWS cli as well

We're using marshmallow to parse whylogs config from YAML

However, Pydantic is much more powerful as it allows users to set config via various mechanims, from YAML, JSON to Environment settings.

We should consider moving to pydantic

Backend probly should return something like HTTP 409 if entity already exists.
