Render daemonsets.podSecurityContext in Helm ClusterPolicy template

[kbix2000]

Render ClusterPolicy daemonsets.podSecurityContext from Helm values

Problem

ClusterPolicy.spec.daemonsets.podSecurityContext is already supported by the CRD and by the operator controller (applyCommonDaemonsetConfig). Helm values such as:

daemonsets:
  podSecurityContext:
    seLinuxOptions:
      type: spc_t
      level: s0

were silently ignored because deployments/gpu-operator/templates/clusterpolicy.yaml never emitted the field.

This breaks SELinux / OpenShift-style deployments that rely on chart values alone (no manual ClusterPolicy edit).

Change

• Render daemonsets.podSecurityContext into the ClusterPolicy when set in values.
• Document the option in values.yaml.

Follow-up request

Global daemonsets.podSecurityContext applies to all operand DaemonSets. We would also like optional per-operand podSecurityContext (e.g. under driver, toolkit, devicePlugin) so SELinux types can be scoped without granting every DaemonSet the same domain. Happy to follow up in a separate PR if preferred.

Test plan

• helm template with daemonsets.podSecurityContext.seLinuxOptions set → ClusterPolicy includes the field under spec.daemonsets
• helm template without the value → field absent
• Install / upgrade: operator applies PSC to operand DaemonSet pod templates
