config-perf: Simplify port-list implementation and fetch exactly needed nets/ips/VMs

[Hampapur Ajay]

Instead of different callers of _port_list() gathering the needed nets/ips/VMs implement this fetch for memo needs within _port_list() definition. So a port list will always involve constant order round-trip times and the fetch is exactly for the data that is needed (fixes the bug where incorrectly all VMs were fetched in below snippet)

- for vmi_obj in all_port_objs:
- if vmi_obj.get_virtual_machine_refs():
- device_ids.append(vmi_obj.get_virtual_machine_refs()[0]['uuid'])
- port_net_objs, port_vm_objs = self._port_net_vm_project(project_id,
- device_ids)

config-perf: build up nets/ips/vms in _port_list with exact fetch

The different callers of _port_list() were building up virtual-networks,
instance-ips and virtual-machines (sometimes getting more than needed
from api-server) as a memo to be used within the request context.
Simplify this by having _port_list() do it and free callers up to
only pass needed ports to _port_list(). Use
a. list by obj_uuids for nets from port refs
b. list by back_ref_ids of ports for instance-ips
c. list by obj_uuids for VMs from port-refs (or port parent for
<1.06 based port creation)

Closes-Bug: #1432767
