1. MGMT-15339: Run network config before NetworkManager …

   Currently the systemd service that we use to apply static network
   configuration from the non-minimal discovery environment wants to run
   after `dracut-cmdline.service` and before `dracut-initqueue.service`.
   But that isn't possible because this service is created by an ignition
   configuration, and services created that way only run after the root has
   pivoted, and at that point the `cmdline` and `initqueue` steps of Dracut
   have already been completed.
   
   The net result is that this ordering dependencies are just ignored, and
   the service will run as part of `multi-user.target` without any special
   ordering restriction. It may even run after NetworkManager. If that
   happens then the configuration files that it generates will be ignored.
   That is unlikely, but it has been observed when there are many network
   interfaces with static configuration. To avoid that the service should
   be explicitly configured to run before NetworkManager.
   
   Note that there is another diferent systemd service that is used to
   generate the network config when using the minimal ISO. That is added
   directly to the initrd, not via ignition. It runs before the root pivots
   because the network is needed to fetch the root file system. This patch
   doesn't change that service.
