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.

The ccsdk-lighty-module artifact contains lighty.io module
that groups all other modules from other repositories and
starts/stops them at once.

The ccsdk-lighty-distribution artifact starts
the lighty.io core, Restconf and the CCSDK integrated with
the lighty.io and creates zip distribution with the CCSDK
lighty.io application and necessary libraries.

The distribution-lighty-ubuntu-docker artifact creates
the docker image with the zip distribution from
the ccsdk-lighty-application artifact and necessary
configuration files.

For more information see the README.md file
in the lighty/docs directory.
