feat: Support for fault-tolerant execution

[dervoeti]

Description

Implementation for #576

When providing credentials for S3, Azure or GCS we currently need a SecretClass. It would be easier if the user could just provide a Secret as an alternative, we had that discussion recently. To be consistent with the current state, I used SecretClass exclusively for now.

Things I did not do in this PR to ease the review process (we could tackle those as a separate PR):

• Combine redundant logic from FTE and Catalog modules
• Use config-utils instead of doing the load_env_from_files stunt

I dropped some comments on the CRD code and YAML.
As an possible alternative I can propose a complex enum style, where we can together think about it, just pasting it here for reference for now

spec:
  clusterConfig:
