Add Persistent Volume Support for LocalDisk ArmorProfileModel Data

[Danny-Wei]

What this PR does

Resolves data accessibility issues in multi-replica manager deployments by adding persistent volume (PV) support for LocalDisk-type ArmorProfileModel objects, enabling data sharing across manager instances.

Key Features Added

• Introduced behaviorModeling.usePersistentVolume Helm value to toggle PV usage for LocalDisk-type ArmorProfileModel data
• Added Helm template configurations for persistent volume integration:
  • Defined persistentVolume settings with configurable PVC claim name (varmor-manager-apmdata-pvc)
  • Maintained existing emptyDir volume as default storage option
  • Updated volume mounts to use shared storage path /var/log/varmor/apmdata across instances

Benefits

• Enables data consistency across manager replicas in multi-instance deployments
• Prevents data loss during leader re-election by centralizing LocalDisk-type ArmorProfileModel data
• Improves reliability of ArmorProfileModel import/export operations across manager restarts
• Provides flexibility to scale storage beyond node-local emptyDir limits

Notes

• Requires manual creation of a PVC named varmor-manager-apmdata-pvc in the manager namespace before enabling usePersistentVolume
• emptyDir remains default with a 500Mi size limit for lightweight deployments
