What happened?

In Python distributed runtime, when a worker runtime disconnects and a new worker runtime connects and register the same agent_type, there will be conflicting subscriptions from the previous connection.

What did you expect to happen?

In distributed agent runtime, the host servicer's SubscriptionManager should support a way to remove subscriptions when clients with the agent_type disconnects.

How can we reproduce it (as minimally and precisely as possible)?

1. Run host,
2. Run worker 1
3. Disconnect worker 1
4. Run worker 2 but register the same agent types in worker 1
