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. Change-Id: Ifb77cfaa6e6472d43295a7c41a49ddd657c0e2c2 Issue-ID: POLICY-1035 Signed-off-by: ramverma <ram.krishna.verma@ericsson.com>
