When creating a snapshot of an 'UltraSSD_LRS' volume using the Azure Disk CSI driver, snapshot creation times regularly exceed the hardcoded 10 minute timeout value, causing the snapshots to fail in OpenShift.

    1. Create a large UltraSSD_LRS based PVC/PV with the disk.csi.azure.com provisioner (e.g. 1TB)
    2. Ensure a significant percentage of the PV contains data
    3. Create a VolumeSnapshot based on the PVC to initiate snapshot creation in Azure

    The VolumeSnapshot creation may fail to complete because the hard coded 10 minute timeout period is exceeded.

    The VolumeSnapshot creation is able to handle arbitrarily longer creation times in the Azure backend (e.g. 60-120 minutes or more) without failing.
