> The only way to currently get the results from tasks ran in Trogdor is
> through listing all of them via the "--show-tasks" CLI command

> {code}
> This can prove inefficient and annoying if the Trogdor Coordinator is
> long-running and we only want to get the results from a specific task.
> The current REST endpoint ("/tasks") for listing tasks enables filtering
> through StartTimeMs/EndTimeMs and supplying specific TaskIDs, but it would be
> cleaner if we had a specific endpoint for fetching a single task. That
> endpoint would also return a 404 in the case where no task was found instead
> of an empty response as the /tasks endpoint would.
> I propose we expose a new "/tasks/:id" endpoint and a new cli command
> "--show-task TASK_ID"
