Partially reviewed. Still need to go through a good portion of OntapVMSnapshotStrategy.java and SnapshotManagerImpl.java

/**

Couldn't find any instance of this being used. Is this needed somewhere?

JobResponse jobResponse = snapshotFeignClient.deleteSnapshot(getAuthHeader(), flexVolUuid, snapshotUuid);

if (jobResponse == null || jobResponse.getJob() == null) {
logger.debug("deleteFlexVolSnapshotForCloudStackVolume: no async job returned for snapshot [{}] "

Also, shouldn't we be treating jobResponse 'null' as HTTP failure?

Aren't we doing SFSR? Shouldn't we rename 'getOntapCloneName' method appropriately?

// All volumes in a VM snapshot belong to ONTAP-managed pools and share the same ONTAP credentials.
If we are assuming this, we need to set this as a pre-requisite to the user. Else, the user might create storagePools from different ONTAPs with different creds.

logger.info("takeVMSnapshot: VM [{}] spans {} FlexVol(s); using temporary CG two-phase snapshot flow",

My understanding from our initial discussion on this approach was that 1CG can be mapped to 1 FV. If this is the case, then why can't we always use createVmSnapshotsViaTemporaryCg? Instead of having createVmSnapshotsViaSingleFlexVol separately for 1FV usecase?
