I would like to add Hypershift / Hosted Control Planes to the set of cluster install types handled by the SiteConfig operator's ClusterInstance.

HCP's HostedCluster CR differs from Image based installs (IBI) and Agent cluster installs (ACI) in that it refers to a release image used to populate two CRs as a bare string, while IBI and ACI both use an object, ClusterImageSet. ClusterInstance uses the ClusterImageSet, but has no way (short of implementing CNF-13214) to access the bare string in the ClusterImageSet for use in templates.

Therefore, I would like to request addition of a bare string releaseImage for use in creating HostedCluster and NodePool CRs.

This more general case would allow creation of a ClusterImageSet template that would handle the releaseImage population and reference based hand-off to IBI and ACI installers.
