Change in ovirt-engine[ovirt-engine-3.6]: core: Live Merge: Improve Live Merge Recovery Mechanism

Tal Nisan has submitted this change and it was merged. Change subject: core: Live Merge: Improve Live Merge Recovery Mechanism ...................................................................... core: Live Merge: Improve Live Merge Recovery Mechanism When sending live merge command, we may fail to get vdsm's response due to network error. In this case, the parent of the volume that should have been deleted (the volume that the data is merged in to) will be marked as ILLEGAL. However, a merge job may have started, and even possibly completed, and we want to allow the user to try live merge again in order to remove the snapshot. When the user tries live merge again, if the volume is already deleted from the chain or if there is a running merge job, vdsm returs 'imageErr' or 'mergeErr', respectively. In this patch, engine catches those errors and continues the merge flow as if it succeeded. If merge succeeded the volume is removed from database. Otherwise, volume stays in ILLEGAL state.
