create base package 'osm_ro_plugin' for plugin

contains base packabe, dummy and failing connectors

All plugins will require this package instead of osm_ro
In that way plugin development is more independent
from main project, and it can be re-used in other projects.
For example openvim can use these SDN plugins without importing osm_ro
