Add metrics to show the number of nodes being tracked

Describe the feature
I'd like to know the number of nodes that a NTH instance is currently managing and have it exported as a metric.

Is the feature request related to a problem?
After the tagging changes we had a defect where the tags weren't being set on the instances causing our nodes to no longer be managed by NTH; this metric would have meant it was easy to see that it wasn't configured correctly.
