This can be done using config overrides in user_variable.yml, for example:
neutron_neutron_conf_overrides: DEFAULT: global_physnet_mtu: 9000 neutron_ml2_conf_ini_overrides: ml2: path_mtu: 1500
Since you need to set container_mtu in openstack-ansible manually, this looks like the best way to configure Neutron.
