    Don't attempt to configure live migration

    When configuring nova containers via puppet, the puppet class chain
    includes a class for live migration, which configures live migration
    aspects in nova and libvirt.

    Some of the libvirt config parts try to notify Service[libvirt], but
    that service definition is only included in nova-libvirt service, it's
    not included in the control plan nova services. However, our hieradata
    is currently global on the node, it's not per-service, which means even
    though only nova-compute and nova-libvirt service set

      tripleo::profile::base::nova::manage_migration: true

    this hiera setting is applied to all containers running puppet, most
    notably the ones which configure nova control plane services. As a
    result, configuration of nova control plane services failed, and in turn
    the whole deployment failed.

    This commit disables the libvirt part of live migration config until we
    implement some better solution (e.g. hieradata separation between
    different puppet containers, or move the libvirt config parts only to
    nova-compute manifests in puppet-tripleo).
