Initial implementation: The init extended flow rule and store interface APIs
The APIs are for supporting service data to install on network devices.
This is related to JIRA ticket ID ONOS-869.
Updated API code and added implementation code files.
Modified API for supporting payload abstruction, and added routing mechanism for pushing flow rules to devices.
Added more javadoc, and fixed some minor issues.
Updated javadoc, removed unnecessary method, and test code.
