Proposal to remove OSGi dependencies from the CCSDK project

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.
