This is a clone of issue
HOSTEDCP-1046. The following is the description of the original issue:
As a user of Hosted Control Planes, I would like the HCP Specification API. to support both ICSP & IDMS.
IDMS is replacing ICSP in OCP 4.13+. hcp.Spec.ImageContentSources was updated in OCPBUGS-11939 to replace ICSP with IDMS. This needs to be reverted and something new added to support IDMS in addition to ICSP.
