Adding code for bootstrapping policy distribution

* Code changes for initializing handlers & related plugins from
configuration parameter JSON file.
* Using common parameter service for refering parameters at multiple
places.
* Moved related parameters classes from "main" to "reception" to avoid maven
cyclic dependency errors.
* Added test cases for new code chnages. The test coverage is around
95%.
* Changed logging from slf4j to common-logging.
