[ONOS-3203] Fault Management fixes.

1) Fix "org.onlab.osgi.ServiceNotFoundException: Service org.onosproject.incubator.net.faultmanagement.alarm.AlarmService not found" runtime error by making  SnmpAlarmProviderService a (annotated) Service.  Possibly later can register it via the ProviderRegistry without the Service anotation.
2) When SnmpAlarmProviderService is deactivated de-register our InternalDeviceListener to avoid leak.
3) In providers/snmp/alarm/pom.xml : Remove unnecessary dependency versions info. Remove unnecessary shading.
