Do not defer allocation if fixed-ips is in the port create request.

Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Do not defer allocation if fixed-ips is in the port create request.

    Fix a usage regression, use case #2 in Nova Neutron Routed Networks spec
    https://specs.openstack.org/openstack/nova-specs/specs/newton/implemented/neutron-routed-networks.html

    Currently ip allocation is always deferred if binding:host_id is not
    specified when routed networks are used. This causes initial fixed-ips
    data provided by the user to be _lost_ unless the user also specify the
    host.

    Since the user specified the IP or Subnet to allocate in, there is no
    reason to defer the allocation.

    a) It is a common pattern, especially in Heat templates to:
     1. Create a port with fixed-ips specifying a subnet.
     2. Create a server and associate the existing port.
    b) It is also common to use Neutron IPAM as a source to get VIP
       addresses for clusters on provider networks.

    This change enables these use cases with routed networks.

    DocImpact: "The Networking service defers assignment of IP addresses to
    the port until the particular compute node becomes apparent." This is no
    longer true if fixed-ips is used in the port create request.

    Do not defer allocation if fixed-ips is in the port create request.

    The above is no longer true if fixed-ips is used in the port create
    request.
