[BUG]: Cert-csi modifies ephemeral.volumeAttributes fields causing test failure

[sakshi-garg1]

Bug Description

cert-csi reads data from the file specified by the --cert-config option in order to execute ephemeral volume testing.

It appears during this read operation, the child field names of ephemeral.volumeAttributes are being converted to lower-case. When the ephemeral volume is then created during the test, csi-powerflex fails to mount the volume because it is expecting the case-sensitive fields of volumeAttributes.

For example:

storageClasses:
  - name: vxflexos-cert-csi
    minSize: 8Gi
    rawBlock: true
    expansion: true
    clone: true
    snapshot: true
    RWX: false
    ephemeral:
      driver: csi-vxflexos.dellemc.com
      fstype: xfs
      volumeAttributes:
        volumeName: "my-ephemeral-vol"
        size: "8Gi"
        storagepool: "SP-SW_SSD-1"
        systemID: "af948d7db6f7160f"

The child fields of storageClasses[0].ephemeral.volumeAttributes are cased, but when cert-csi prompts the user to confirm the test cases are correct before starting the test run they are displayed as below with lower-cased field names.

[2024-12-19 16:07:53] INFO 9. EphemeralVolumeSuite {driver: csi-vxflexos.dellemc.com, podNumber: 2, volAttributes: map[size:8Gi storagepool:SP-SW_SSD-1 systemid:af948d7db6f7160f volumename:my-ephemeral-vol]}
This effects cert-csi v1.4.0 onward.
