If I run tail -f <pubsub> on a GCP Pub/Sub, then Ctrl-C and exit Wash, I get

WARN API: Shutdown failed: context canceled

I expect no warning.

Avoid shutdown race when handlers are slow to finish
13d86e2 
When `Shutdown` is called on a net/http `Server`, it causes the `Serve`
function to return but may still have further cleanup to do. The
previous implementation sent a signal that shutdown was complete once
`Serve` returned, which would cancel a timeout context. If the server
was still actually cleaning up, we might get an error from `Shutdown`
because the context it was using was canceled.

Close the stopped channel once `Shutdown` returns to trigger cleanup.

Fixes puppetlabs-toy-chest#711.
