    neutron: only list ports if there is a quota limit when validating
    
    The list_ports call can take awhile if the project has a lot of ports.
    If it turns out that there is unlimited quota, then we don't even need
    to list the ports, so move that after the show_quota call.

Title:
  nova.network.neutronv2.api.validate_networks could be smarter when
  listing ports

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  There are two things we can do to make this more efficient:

  https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L1182

  1. Move the list_ports call after the unlimited quota check - if the
  quota is unlimited, we don't need to list ports.

  2. Filter the list_ports response to only return the port id, we don't
  need the other port details in the response since we don't use those
  fields, we're just getting a count.
