- Added hosts to test data.
- Messed with colors and icons.
- Added more internal configuration values.

 * Use the new class EventMetric to cleanup and simplify the implementation
 * Replaced the single metric for Topology Events with four metrics
   (last event timestamp and event rate):
   - Device Event metrics
   - Host Event metrics
   - Link Event metrics
   - Topology Graph metrics

- IMap#get usually returns clone of original value,
  but when the type is byte[], it returns the original value.
- During the deserialization process, Kryo temporarily modifies the input buffer,
  which may cause problem when multiple threads were reading the same value.

- applying clone only to value deserialization for now,
  since it is unlikely that caller will be modifying Map key

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     module for each event type: SUBMITTED, INSTALLED, WITHDRAWN.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

Devices, Hosts, Links, TopologyEvent

Now the semantics for updating the metrics are:
 * Any topology-related event (DeviceEvent, HostEvent, LinkEvent,
   TopologyEvent) will update the Lost Topology Event Timestamp
 * Only the DeviceEvent, HostEvent and LinkEvent will be counted in
   measuring the event rate; TopologyEvent is excluded, because it
   is generated as a result of some of those events

Also, increased the number of saved events from 10 to 100.

Fixed the optical config json file.
Fixed treatment of links added by ancillary providers.
Added a trap for topology provider errors.
Added CLI to recompute topology.

AbstractEvent.toString()

This method is needed so we can display the port as well (when set).
