Proposal to remove OSGi dependencies from the CCSDK project
Dependencies on the OSGi frameworks and libraries are removed by integrating the CCSDK project with the lighty.io. It's a toolkit that allows to use ODL services (in this case core services and the Restconf) without the dependency on the Karaf framework and the Blueprint DI. In this change are created the lighty.io modules which initialize and expose same services as the Blueprint DI in the blueprint.xml files.
