[Feature] support ephemeral models + python models #12254
Description
Is this your first time submitting a feature request?
- I have read the expectations for open source contributors
- I have searched the existing issues, and I could not find an existing issue for this feature
- I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion
Describe the feature
- python models that reference ephemeral SQL models
- python models that are themselves ephemeral
