Remove deprecated network_device_mtu option

[OpenStack Infra]

Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Remove deprecated network_device_mtu option

    The right way to configure Neutron to work with infrastructure MTU is by
    using plugin agnostic global_physnet_mtu and ml2 specific
    path_mtu/physical_network_mtus options. The deprecated option is error
    prone and does not allow to use different MTUs per network.

    DocImpact Remove all references to network_device_mtu option from
              Neutron documentation. Note that Nova has a deprecated option
              with the same name that will need a separate patch to be removed.

    Remove the last notion of Neutron network_device_mtu option

    This seems like the only place in doc tree that mentions the option that
    is worth a manual cleanup. Other places are autogenerated.
