Add internal_info field to ports and portgroups

In case of ports, it is also added to the API, as a readonly field.
It will be used for any port-specific internal information ironic
needs to store inside the port object. In this change we start using
it to store UUIDs of the cleaning ports that ironic creates, instead
of fiddling with port.extra['vif_port_id'], as extra is intended for
operator use only.

Partial-bug: #1526403
