> Don't delay kill sequence when HTTP teardown signal could not be dispatched

> Key: AURORA-1275

> Project: Aurora
> Issue Type: Story
> Components: Executor, Thermos
> Reporter: Stephan Erb
> Assignee: Stephan Erb
>
> The Thermos task runner performs a kill escalation sequence by dispatching
> calls to the HTTP endpoints /quitquitquit and /abortabortabort before
> stopping a task for good. After each of these calls it waits for 5 seconds.
> The runner should not perform the waiting when the corresponding shutdown
> request could not be dispatched.
> Advantages:
> * Services which use a health port but don't implement /qqq and /aaa are not
> taxed by a total of 10 seconds waiting time for each kill operation
> * The whole system is faster to react when services are meant to be restarted
> due to failing health checks. Failing health checks often imply an
> application is not responding at all, including the endpoints /qqq and /aaa
