[x] interface_automation allocate primary IPs enable switch flipped (`PRIMARY_IPS_ENABLED`). (At the same time of the 2nd cutoff date in [1])
[x] all primary IPs imported to Netbox (prior to the 2nd cutoff date in [1])
[x] decide policies for frack import
[x] decide policies for other outliers (OIT, RIPE Atlas)
[x] interface_automation/import puppetdb works with ##PRIMARY## interfaces post-puppet
[x] interface_automation/import puppetdb allows manual fact injection for pre-puppet phase reimage [not needed for now but already implemented]
[x] decommission cookbook deletes all non-mgmt ips and interfaces [ @Volans ]
[x] document workflows
[x] decide timelines [cutoff date decided and announced]
[x] Solve potentially circular dependency in Ganeti VM creation [the machine must exist in Netbox before the IP may be allocated, so makevm must be altered to perform the setup tasks there]
[x] patch wmf-auto-reimage to run the puppetdb import script for a single host after the first puppet run, how to handle failed scenarios
