refactor: Tidy up Nutanix CSI with consistent apply strategy

Move the current logic out to a helm addon strategy as done in other providers.

Also move Helm release to kube-system to be consistent with other CSI providers.

And tidy up flag names to use `--csi.nutanix.` prefix for flags, including wiring
up to Helm chart values and deployment.

Finally, add e2e test for CSI deployment in Nutanix infra.
