When a registry mapping is configured in a HostedCluster via .spec.imageContentSources, that registry mapping should be distributed to worker nodes via the ignition payload. However, the ICSP of the management cluster is getting sent to the workers and not the one from the spec.

    1. Install hypershift on a management cluster that uses ICSPs for its registries.
    2. Create a HostedCluster that specifies a set of different ImageContentSources in its spec
    3. Inspect registry configuration in worker nodes (/etc/containers/registries.conf)
    

    Registry configuration from the management cluster's ICSP is reflected in the registry configuration.

    Registry configuration from the HostedCluster.spec.imageContentSources is reflected in the registry configuration.
