When creating a config-image, extra manifests can be added to 'openshift' dir.
But, since the yamls files are being copied as-is, files with multiple objects are not splitted. Hence, these extra manifests are passed as-is to AI, which results with only the first object being applied.

Note: this is a different behaviour from the full ignition creation which handles this scenario: https://github.com/openshift/installer/blob/8b1b6633dcd8342754f827698214a6a7ce240ade/pkg/asset/agent/image/ignition.go#L451

100%

1. Add a yaml file with multiple objects to 'openshift' dir
2. Create the config-image (openshift-install agent create config-image)

The yaml file is added as-is to 'extra-manifests' dir in the config image.

The yaml file should be splitted to multiple yaml files.
See: https://github.com/openshift/installer/blob/8b1b6633dcd8342754f827698214a6a7ce240ade/pkg/asset/agent/image/ignition.go#L451

I.e. Instead of being copied as-as:
