Add PCI address information to BMH status.hardwareData

[alknopfler]

User Story

As a user I would like to have access to PCI address information to be able to pre-configure pci accelerator cards (like acc100), e.g cluster hardware information can be used at the deployment phase to optimally configure workloads such as telco network functions.

Detailed Description

IPA is retrieving the pci address info included in /sys/bus/pci/devices but only the nics and disk are shown in the bmh object:
https://github.com/openstack/ironic-python-agent/blob/e9c0578c7d30ae97ad01ea52029cb7368433c0dc/ironic_python_agent/inspector.py#L339

So when the related information is available it would be good to propagate it to the BMH status.hardwareData

BMH status.hardwareData

is deprecated, any new additions should go to the separate HardwareData CR.

I don't object to this addition, but we need a proper discussion around the API we introduce and the user story we implement with it. Ideally, a design proposal.

Accepted with the same caveat as in @dtantsur 's comment.
