feat(ironic): panos driver base - PUC-2049

[khackworth]

Adding in the scaffolding for the PAN-OS driver.

• panos_hardware.py - Hardware type registration with standard Ironic interfaces
• panos_inspect.py - Inspection interface with 3-password credential fallback (standard → preconfig → factory)
• panos_management.py - Management interface (power, boot device operations)

Added in tests to accommodate what was intended. Secrets are set to soft fail if undercloud_deploy isn't released for that env.
