Added a new module: ONOS intent metrics application

It can be used as an Intent-related event and event metrics collector.
It can be loaded by one of the following two (new) features:
     onos-app-metrics, onos-app-metrics-intent

After loading the module, it subscribes for intent-related events
and keeps the following state:
 (a) The last 100 events
 (b) The timestamp of the last event (ms after epoch) as observed by this
     module for each event type: SUBMITTED, INSTALLED, WITHDRAWN.
     The missing event type is the equivalent of "Withdraw Requested"
 (c) The rate of each intent event type: count, median rate, average rate
      over the last 1, 5 or 15 minutes

The following CLI commands are added:
 * onos:intents-events
   Shows the last 100 intent events
 * onos:intents-events-metrics
   Shows the timestamp of the last event (ms after epoch) as observed by
   this module for each event type, and the rate of the topology
   events (for each event type): see (b) and (c) above
