[VOL-2404] : RW-Core changes for handling OLT Reboot Scenario
- When the OLT's connection status goes from REACHABLE to UNREACHABLE
in ENABLED/DISABLED admin state, delete all the logical ports,
child devices, logical device and device flows.
- When OLT's connection status becomes reachable again, child devices,
ports will be re-discovered again. The logical device will be recreated
again.
- Will not handle the case where OLT goes UNREACHABLE when OLT is disabled
as part of voltha2.3 release
