artifactapi pulls its own images from itself, so a cold boot with every api pod down cannot pull them. Kubelet GC never removes images referenced by pods on the node, so a pod on every node holding the pinned tags keeps them local.
- add image-keeper DaemonSet referencing the api and ui images as no-op init containers
- run a static busybox as `true` inside the distroless api image
- tolerate all taints, run at low priority with tiny non-root resources
