Update optimizing RegisteredServicesCache ServiceInfo parsing

1.Use component name as the cache key instead of an ad-hoc
constructed string.
2.If no services are asked within 30 seconds, the cache will be
cleared. If the services are asked within 30 seconds, it will
reset the timer to 30 seconds again.
3.Move the logic to read or update the cache in generateServicesMap.
