MTV-6511 | Gate collection of custom attributes in vSphere inventory

[vdudejon]

Summary

Adds INVENTORY_VSPHERE_EXCLUDED_VM_PROPERTIES environment variable to allow operators to exclude specific VM properties (e.g. customValue, availableField) from the vSphere PropertyCollector PathSet.

Key Changes

• Adds VsphereExcludedVMProperties to pkg/settings/inventory.go (INVENTORY_VSPHERE_EXCLUDED_VM_PROPERTIES).
• Adds filterVmPathSet() and critical property denylist enforcement to pkg/controller/provider/container/vsphere/collector.go.
• Related to PRs MTV-6511 | Split Custom Field Definitions from VM table in inventory to dedicated table #8250 and MTV-6511 | Fixes performance regression from #8250 #8367.
• Adds unit tests in collector_test.go and inventory_test.go.

Resolves: MTV-6511

Changes

vSphere property exclusions

Layer / File(s)	Summary
Inventory exclusion setting pkg/settings/inventory.go, pkg/settings/inventory_test.go	Adds INVENTORY_VSPHERE_EXCLUDED_VM_PROPERTIES, stores the configured property paths, and parses comma-separated values with whitespace trimming.
Collector PathSet filtering pkg/controller/provider/container/vsphere/collector.go, pkg/controller/provider/container/vsphere/collector_test.go	Filters configured properties from the VM PathSet, preserves migration-required properties, logs warnings for protected exclusions, and tests the behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to e5cf1

The PR adds configurable exclusion of non-critical vSphere VM properties while preserving migration-required fields. No direct user-facing production risk is identified, but the environment-variable test should restore prior state to avoid order-dependent test failures; the change is otherwise mergeable with that follow-up.

if we are adding new parameter to the inventory INVENTORY_VSPHERE_EXCLUDED_VM_PROPERTIES we should add it also to the operator so it can be configured via ForkliftController
