Send callback message to clients which set callback

- Requirements:
Server wants to send required IPC message when service state is changed.

- Solution:
Through previous commit, callback registration information was added.
Using this new information, server can decide whether the client require
to receive service state changed event. This patch adds checker for
deciding whether client regists callback.
