Public bug reported:

Using ipam_driver=infoblox in neutron.conf, create subnet fails with
following error:

Further verified code in ipam_pluggable_backend.py file and observed
following code:

        # TODO(kevinbenton): remove after bug/1666493 is resolved
        if subnet['id'] != ipam_subnet.subnet_manager.neutron_id:
            raise RuntimeError(
                "Subnet manager doesn't match subnet. %s != %s"
                % (subnet['id'], ipam_subnet.subnet_manager.neutron_id))

As ipam_subnet.subnet_manager is defined specific to the neutron default
ipam driver at
https://github.com/openstack/neutron/blob/stable/pike/neutron/ipam/drivers/neutrondb_ipam/driver.py#L129
, it should not be used in generic file such as
ipam_pluggable_backend.py which is used by other ipam_drivers.
