    Allow region setting for ironic-neutron-agent

    The "os_region" param is missing in the ironic_neutron_agent.ini.j2
    file. Without specifying the region, the neutron service will randomly
    pick a region for the ironic-neutron-agent. Therefore, a list of
    incorrect agents might be created in the neutron database "agents"
    table for nodes from other regions. To list all neutron agents, use
    'openstack network agent list'.
