Orchestrators with persistent state

[mirek-capgemini]

Docs are covering different types of orchestration. https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/agent-orchestration/?pivots=programming-language-python
I want to store conversation state persistently so i can came back to conversation later, or from different instance of agent. Maybe creating own runtime is the way to go, but i cannot find docs how i could create one.
