### Which jobs are failing?

master-informing:
- [gce-cos-master-serial](https://testgrid.k8s.io/sig-release-master-informing#gce-cos-master-serial)

### Which tests are failing?

- Kubernetes e2e suite.[It] [sig-autoscaling] DNS horizontal autoscaling [Serial] [Slow] [KubeUp] kube-dns-autoscaler should scale kube-dns pods when cluster size changed
- Kubernetes e2e suite.[It] [sig-cloud-provider-gcp] Nodes [Disruptive] Resize [Slow] should be able to add nodes
- Kubernetes e2e suite.[It] [sig-cloud-provider-gcp] Nodes [Disruptive] Resize [Slow] should be able to delete nodes
- Kubernetes e2e suite.[It] [sig-cloud-provider-gcp] [Disruptive] NodeLease NodeLease deletion node lease should be deleted when corresponding node is deleted

### Since when has it been failing?

After https://github.com/kubernetes/kubernetes/pull/124519

### Testgrid link

https://testgrid.k8s.io/sig-release-master-informing#gce-cos-master-serial

### Reason for failure (if possible)

```
provider does not support InstanceGroups
```

### Anything else we need to know?

Support for gce instance groups was removed, so these tests need to be either updated (To test some other functionality) or removed.
