Problem:
When calling newQueue metrics can be of type noMetrics when just calling
New. When doing this a new goroutine is created to update the metrics
but in this case there are no metrics so it's just creating goroutines
that don't do anything but consume resources.
Solution:
If the incoming metrics is of type noMetrics, don't start the goroutine
