Type Alias SharedDescribe 

pub type SharedDescribe = Shared<BoxFuture<'static, Result<ManagerRuntime, Arc<Error>>>>;

One Manager.Describe call, awaited by every collector that needs it.

The first collector to poll it drives the call; the rest wait on that same result. Shared needs a cloneable output, hence the Arc around the error.
