Adds prometheus metric exporter (optional) to Store #5

When passing --prom=<host>:<port>, a prometheus metrics exporter will be made available.

There are limitations due to performance and current design. It only really reports the number of namespaces, and some metrics for the namespaces which were randomly garbage collected during the last run.
