Enable/Disable service bus triggered function at runtime

Implementing a Circuit Breaker pattern, for a service bus triggered function, today requires a secondary app (Logic App or Azure Function) to disable your function app in order to stop processing when your circuit breaker triggers.

It would be nice if we could prevent the need of a secondary app to start/stop your function app by allowing us to enable/disable a service bus triggered function at runtime while still running the function app with possible other functions inside of it.

Let me know what you guys think :)

Start by reviewing the Azure Functions host/runtime areas that handle Service Bus-triggered functions, then compare the Polly-Contrib circuit-breaker and durable-actor references in the issue. Done means a function can be enabled or disabled at runtime independently while the app and its other functions continue running; the issue does not name specific files or tests.
