Provide a recommended way to pass configuration into workflow

If dependency injection into the workflow is discouraged, we need to provide a way for an external code to pass all kinds of configurations into Workflow instances. A potential solution to ensure determinism could be implementing it on interceptors level and storing configuration into a (mutable?) side effect and providing a set of handy utility methods (Probably on Workflow) to access it in the workflow implementation.

Start by reviewing how Workflow instances currently receive configuration and how interceptors are used. Clarify whether configuration should be stored as a mutable side effect and which utility methods on Workflow are required; done means a documented, deterministic way for external code to provide configuration without dependency injection.
