Expose pool metrics #27
Description
We are running pooled-jms in kubernetes and it would be useful to have jms pool metrics (e.g. number of active / idle connections and sessions per pool) so we can monitor what's going on in our pods.
I noticed that micrometer by default already exposes all pool metrics, but they expect that jmx is enabled.
So I think that a feature to enable jmx on the pool would work for us as well.
