Describe the solution you'd like

Currently, if we have different crew, then we will need to have seperate task yaml for the crew base model but agent.yaml can be shared.
As using flow allow us to have multiple crew running in the same flow, sharing tasks & agent yaml in the context of flow will make more sense as compare to pre-flow structure.

Describe alternatives you've considered

Or create agent_base and task_base with all agent and task created, then load into crew base and config
