This PR adds the number of currently active instances in the pool as a gauge, very much like the exisiting
num.idle
gauge.(...I had to refactor the test a little bit. The "dangling" pool instances made the test very flaky. If you have a cleaner/nicer solution than try-with-resources I'm open for it 👍 )
