Asynchronous tasks can only be submitted while the IPA is running. Further more, the shutdown sequence can not be tracked with a simple running flag. We can also be in the state 'Stopping' where we have not yet completed all events, but we must not commence anything new. Refactor the running_ boolean into a stateful enum to track this.
