ml2-ansible deployment fails with error

[Rabi Mishra]

We enable OVN services by default for controller roles and they are not mapped to OS::Heat::None[1] (as ovn is the the default). environment/neutron-ml2-ansible.yaml should have been changed when we moved from ovs to ovn as the default.

    Change NeutronMechanismDrivers in ml2-ansible environments

    This should have been done when we moved to ovn as the
    default.

    Note: Not sure why we maintain two different environments.
    Probably should remove one in a subsequent patch.
