objects: adding a parent_addr field to the PciDevice object
The parent_addr field will help identify the relationship between
Physical and Virtual pci device functions.
This information was already available to the PciDevice objects and was
stored in extra_info['phys_function'] field, so we add code that will
migrate old data on the fly, for live upgrade scenarios where we still
have running older compute nodes alongside new ones.
We don't want to migrate, however, if there are still any API service
instances running that might access this info directly (without the help
of the conductor) but have not been upgraded yet.
