What type of PR is this?
cleanup

Which issue does this PR fix:
#2567

What does this PR do / Why do we need it:
The aws-node ClusterRole does not have WATCH permission for CNINode resources as IPAMD has no need to cache these objects, and it consumes excess memory to cache them. By passing the CNINode scheme to the cache, controller-runtime was issuing a WATCH, which resulted in the following log:

E0914 13:07:56.908969      12 reflector.go:148] pkg/mod/k8s.io/client-go@v0.27.3/tools/cache/reflector.go:231: Failed to watch *v1alpha1.CNINode: unknown (get cninodes.vpcresources.k8s.aws)

The log is harmless, but we want to avoid it, so this PR does not pass the CNINode scheme to the cache.

If an issue # is not available please add repro steps and logs from IPAMD/CNI showing the issue:
N/A

Testing done on this change:
Manually verified that the pod-eni integration test suite passes and that the log is no longer present.

Automation added to e2e:
N/A

Will this PR introduce any new dependencies?:
No

Will this break upgrades or downgrades. Has updating a running cluster been tested?:
No, Yes

Does this change require updates to the CNI daemonset config files to work?:
No

Does this PR introduce any user-facing change?:
Yes

Stop trying to cache CNINode resources.
