Ignoring this warning because this usage of "bare-metal" complies with the guidance from the SSG.

==== Heterogeneous node pools on agent hosted clusters
For hosted clusters on a bare-metal platform, you can complete disaster recovery tasks by using {oadp-short}, including backing up the data plane and control plane workloads and restoring either to the same management cluster or to a new management cluster.

Hi @SNiemann15 - This PR adds the release notes for HCP for 4.19. I believe the bug fix content for OCPBUGS-52323, OCPBUGS-46037, OCPBUGS-54178, and OCPBUGS-54819 is related to IBM platforms. Can you suggest QE reviewers for that text?

@lahinson Would it be typical to call out the tech preview of HCP on RHOSP in these beyond the table change?

If not, feel free to ignore this. :)

@maxwelldb Good question. I think it's worth calling out. If you have text handy, I can add it to this PR.

@maxwelldb I found the release note text that you added to the OCP 4.19 release notes, and added it here. I hope that's okay!
