feat(usb): NodeUSBDevice controller

[danilrwx]

Description

Added a new CRD NodeUSBDevice and controller for managing USB devices at the node level in the cluster.

Why do we need it, and what problem does it solve?

The DRA (Dynamic Resource Allocation) system automatically discovers USB devices on cluster nodes and creates ResourceSlice resources. However, there was no convenient mechanism for managing these devices at the Kubernetes level:

• No way to see all USB devices discovered on cluster nodes in a unified view
• No ability to assign devices to specific namespaces for use in virtual machines
• No automatic synchronization between devices on nodes and USBDevice resources in namespaces

Solution:

NodeUSBDevice provides an abstraction layer between physical USB devices on nodes (represented via ResourceSlice) and logical USBDevice resources in namespaces. This enables:

• Administrators to see all available USB devices in the cluster via kubectl get nodeusbdevices
• Assigning devices to specific namespaces by setting spec.assignedNamespace
• Automatic creation of USBDevice resources in namespaces upon assignment, simplifying device usage in virtual machines

What is the expected result?

• NodeUSBDevice resources are automatically created for all USB devices discovered by the DRA system
• The Ready condition correctly reflects device presence on the node
• When assignedNamespace is set, a USBDevice is automatically created in the specified namespace
• When assignedNamespace is changed or cleared, corresponding USBDevice resources are correctly deleted
• All device attributes (vendorID, productID, manufacturer, product, etc.) are correctly synchronized from ResourceSlice

Checklist

• The code is covered by unit tests.
• e2e tests passed.
• Documentation updated according to the changes.
• Changes were tested in the Kubernetes cluster manually.
