Pipeline builder needs to instantiate DatasetTypes which depend on StorageClass (and they both are configured via task config). We want to keep pipeline builder independent of butler but that means that initialization of StorageClassFactory becomes an issue. DM-15850 adds support for loading all standard StorageClasses (which come from a standard YAML config) but any non-standard configuration will become an issue in this approach.

I want to see how we can solve this problem by either pre-loading non-standard config for the factory or avoiding its use entirely.
