When updating/upgrading to OVN DVR, old Neutron ML2/OVS L3 and Metadata agents are still running

[Daniel Alvarez]

When using the DVR OVN environments, Neutron metadata and L3 agents could
be left running on the overcloud compute nodes if we come from a DVR ML2/OVS
environment. We need to nullify those resources to make sure that they're
disabled.

    Prevent Neutron L3 and Metadata agents from running when using OVN DVR.

    When using the DVR OVN environments, Neutron metadata and L3 agents could
    be left running on the overcloud compute nodes. This patch explicitly
    nullifies the DVR versions of those Heat resources to ensure they are
    disabled.
