If an 'UltraSSD_LRS' Azure volume snapshot is deleted in OpenShift and the delete fails to succeed in Azure, then the VolumeSnapshotContent resource appears to get stuck in a Deleting/Terminating state until the 'openshift-cluster-csi-drivers/azure-disk-csi-driver-controller' pods are restarted.

    1. Create a snapshot of an UltraSSD_LRS Azure Disk volume with a large amount of data.
    2. After starting the snapshot, and before the snapshot is able to complete in Azure, delete the snapshot in OpenShift.
    3.
    

    The VolumeSnapshotContent object gets indefinitely stuck in a Deleting/Terminating state until the azure-disk-csi-driver-controller pods are restarted.

    The Terminating VolumeSnapshotContent object would eventually reconcile with the Azure backend resource and get removed without a restart of the disk-csi-driver-controller pods being required.
