Support configuration of CON MO Groups/Paths from VTY
The code for supporting the configuration of the OM2000 CON (LAPD Concentrator) MO was so far incomplete and not used from the OM2000 FSM initialization. This patch adds * VTY commands for configuration of CON Groups and Paths * The FSM integration to actually configure the CON MO Change-Id: I56dc1b5e35adef3a2078bcf9536537eb0f454192
