Metrics format

Now you can get counters and histograms recorded in Kamon in the following format:

• Counters

name="circuit-breaker-<circuit breaker name>", tags={eventType=[successful-call][failed-call][circuit-open][circuit-closed][circuit-half-open][call-timeout][short-circuited]}

• Histograms

name="circuit-breaker-elapsed-time-", tags={eventType=[successful-call][failed-call][call-timeout]}

You can now use any Kamon reported library of your preference (e.g. prometheus)
