Add DRA support to ordered-upgrade state machine

[TomerNewman]

Summary

• Extend the NodeLabelModuleVersionReconciler to handle DRA modules through the same ordered-upgrade label action table used by device plugin modules, adding a new version-dra node label prefix
• Parameterize getLabelAndAction with a role-specific label function so the existing state machine works for both device plugin and DRA without duplication
• Make the DRA reconciler version-aware: include version-dra in DaemonSet node selectors, create per-version DaemonSets (to avoid immutable selector errors on upgrade), and garbage collect old-version DaemonSets

Changes

• internal/constants/constants.go — new DRAVersionLabelPrefix constant
• internal/utils/kmmlabels.go — new GetDRAVersionLabelName, IsDRAVersionLabel; refactored GetNodesVersionLabels to use IsVersionLabel
• internal/controllers/node_label_module_version_reconciler.go — added isDRA/draVersionLabel fields, setModulesDRAStatus (with graceful fallback when Module CR is deleted), getDRAPods via shared getDaemonSetPods helper, resolveLabel for role dispatch
• internal/controllers/dra_reconciler.go — version label in DaemonSet labels + node selector, getExistingDRADSFromVersion, handleDRA version-aware creation, garbageCollectDRADaemonSets
• Tests updated across all changed files with full DRA path coverage

Test plan

• Unit tests: 385 controller specs, 44 utils specs — all passing
• go vet and go build ./... clean
• E2E on Minikube: deployed v1 DRA module (kmm_ci_a), upgraded to v2 (kmm_ci_b) via version-module label change, verified full label transition sequence, DRA DaemonSet lifecycle (new DS created, old GC'd), and kernel module swap via lsmod — zero controller errors
