Fix functionality of remote service in Notification service.

Fix functionality of remote service in Notification service.

Functionality of parsing address is fixed in the consumer service.
When NSConsuemrEnableRemoteService() was called,
address parsing module used fixed for flags(transport type and secured).
And, consumer service was used previous version of prefix("/di")
for using remote service.

In this patch,
1. Whatever tcp or udp and secured or not, using ipv4 or v6,
   address will be parsed effectually.
2. Prefix of Remote service was modified to "/oic/route" from "/di".
