[ODTN] Interface of a new driver behavior for checking internal connectivity in a device.
This would be used mostly for optical devices which typically have many connectivity constraints.
The patch also includes a CLI command to using driver behavior and an empty driver implementation.
patch 1: first draft: behaviour, CLI, empty driver, xml.
patch 2,3,4,6: checkstyle.
patch 5: comments by Andrea.
