    Also set nova::network::neutron::dhcp_domain

    https://review.opendev.org/#/c/659394 set dhcp_domain
    config with metadata manifest, but still nova hosts have dhcp_domain
    set to default i.e. novalocal. Until it's clear why api/dhcp_domain
    set in nova_metadata volume is not entertained by nova, let's set
    nova::network::neutron::dhcp_domain also to ''.
