In change Ib22753aa6ae0fedce7fb9ecf63f135fda0185c5b the port data model
was updated to include a physical_network field, but this was not
exposed to the user by the REST API. This change exposes the
physical_network field in the REST API.
The port CRUD notification object has been updated to include the
physical_network field.
The API reference and user guide have been updated to include
information about the ports' physical network field.
The API microversion has been bumped to 1.34. During a rolling upgrade
from Ocata when the API service is pinned, the port physical network
field is hidden from API responses, and API requests including the field
are rejected.
