feat: Add driver.labels option to helm chart for CSIDriver resource

[Copilot]

What type of PR is this?

/kind feature

What this PR does / why we need it:

Adds driver.labels option to the helm chart, enabling custom labels on the CSIDriver resource.

This is needed for OpenShift environments where ephemeral CSI volumes require the security.openshift.io/csi-ephemeral-volume-profile label to use the restricted security profile instead of the default privileged profile.

Changes:

• Added driver.labels: {} to values.yaml
• Updated csi-smb-driver.yaml template to conditionally render labels
• Regenerated helm package
• Added driver.labels example to E2E_HELM_OPTIONS in Makefile for e2e testing

Usage:

driver:
  labels:
    security.openshift.io/csi-ephemeral-volume-profile: restricted

Or via CLI:

helm install csi-driver-smb ... \
  --set driver.labels.testlabel=testvalue

Which issue(s) this PR fixes:

Fixes #988

Requirements:

• uses conventional commit messages
• includes documentation
• adds unit tests
• tested upgrade from previous version

Special notes for your reviewer:

Pattern follows existing podLabels implementation. No labels rendered when driver.labels is empty (default).

Release note:

Add driver.labels helm value to set custom labels on CSIDriver resource

Original prompt

This section details on the original issue you should resolve

<issue_title>Allow setting labels for CSIDriver resource from helm charts</issue_title>
<issue_description>Is your feature request related to a problem?/Why is this needed
I want to use ephemeral CSI volumes on OpenShift, but this requires the privileged security profile by default.

It is however possible to change this for a specific driver by setting the following label on the CSIDriver resource:

kind: CSIDriver
metadata:
  name: smb.csi.k8s.io
  labels:
    security.openshift.io/csi-ephemeral-volume-profile: restricted 

See https://docs.okd.io/4.18/storage/container_storage_interface/ephemeral-storage-csi-inline.html

Describe the solution you'd like in detail
It would be nice if this label could be set using Helm values, e.g. driverLabels similar to how Pod labels can be configured with podLabels.

Describe alternatives you've considered
The alternative would be to set the label manually after installation but this is not a robust solution.

Hi @Copilot. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@copilot can you add an example helm chart option here for e2e test?

csi-driver-smb/Makefile

Line 47 in 6d87abf

E2E_HELM_OPTIONS ?= --set image.smb.repository=$(REGISTRY)/$(IMAGENAME) --set image.smb.tag=$(IMAGE_VERSION) --set controller.runOnControlPlane=true
