Ai 1280 conditional flows

[ncapek]

This PR implements the following changes to flow tools:

1. refactor related to new models in Configuration models
2. add the conditional flow config schema
3. updates tools to handle conditional flows

Approving. I still think we might not need to maintain all the classes for the Conditional Flow configuration and using just the schema could be a simpler and more efficient approach.

Additionally, we should assign a new task addressing the refactoring for the client.py module as it got very large to split it into more submodules with individual api models.
