Usually the manifests assets (ClusterImageSet / AgentPullSecret / InfraEnv / NMStateConfig / AgentClusterInstall / ClusterDeployment) depends on OptionInstallConfig (or eventually a file on the asset dir, in case of ZTP manifests). We'll need to change the assets code so that it could be possible to retrieve the required info from ClusterInfo asset instead of OptionalInstallConfig). This may impact the asset framework itself.

Another approach could be to stick this info directly into OptionalInstallConfig, if possible
