Description
Context
I want to share a bean between different steps of the same flow (and dies just after the flow has ended). I wanted to use the @JobScope but it doesn't support multi-threading. I'm wondering if we can add a @FlowScope which support multi-threading.

Research direction
Start by examining the existing @JobScope behavior and how flow steps share context, especially under multi-threading. Define how a proposed @FlowScope would be created, shared between steps, and destroyed after the flow ends; done means the scope supports the stated lifecycle and multi-threaded use.
