O1 Adapter

This MR, adds the O1 Adapter functionality.

To build the adapter

cd adapter
build-adapter.sh --adapter --no-cache

To run the adapter

cd adapter
start-adapter.sh --adapter

To configure the onap/telnet IPs, change the adapter/docker/config/config.json file.

Note: with the current implementation you need to rebuild the image upon configuration change. In the future, this will be changed to get the conf during container init time.
