CI is failing with out of space

It manifests in several different ways but looks something like:

```
 Warning  FailedCreatePodSandBox  43s   kubelet            Failed to create pod sandbox: rpc error: code = Unknown desc = failed to create containerd container: failed to create prepare snapshot dir: mkdir /var/lib/containerd/io.containerd.snapshotter.v1.overlayfs/snapshots/new-3941906082/fs: no space left on device
```
