Ben McIlwain 658f31933c Add metrics for the new Check API ...

New metrics are necessary because the new API no longer wraps
an EPP flow, therefore does not get metrics for free.

Metrics include
 - An EventMetric for processing time
 - An IncrementableMetric for request count, with
   availability (available/reserved/registered) and
   pricing (standard/premium) fields
