Description

If a flow operation fails, the OLT adapter should return an error to the core.
OLT adapter should roll back itself from a failure, and leave a clean environment for a possible retry or reprovisioning.
Free gemPort, send gemPortDelete request to the ONU adapter after the gem port is removed from the OLT.
Remove US/DS scheduler/queues if and only if gemports of the related instance are not used by any flows, and the associated alloc-id is not used by other UNI ports.

[VOL-4478] If a flow operation fails, the OLT adapter should return an error to the core.: Gerrit Review:

[VOL-4478] Error Handling Changes * clearResources method has been updated: - After the gem port is removed from the OLT, free gemPort-id, update gem-related cache data, send gemPortDelete request to the ONU adapter. - Remove US/DS scheduler/queues if gemports of the related instance are not used by other flows, and the associated alloc-id is not used by other UNI ports. - Remove US/DS scheduler/queues if the related US/DS meter exists. So, meter removal is now in the CreateSchedulerQueues method. It still covers ATT use case. - Free alloc-id after the US scheduler is removed from the OLT. * DeleteFlowIDsForGem method has been updated: - Firstly, remove the data from the DB. Then, update the cache. Change-Id: I1ba4a73e0ae55b59caf7216d873bbac7fdedd295: Gerrit Review:
