Register baremetal provisioning ports

[zaneb]

These two ports are used on control plane nodes to cache files that must
be served as part of provisioning baremetal hosts via the
baremetal-operator.

Should we register the port for Ironic too?

[zaneb]

Yeah, and inspector, conductor, mariadb...

Thanks, sorry a couple more things.

• Can we mention for the ironic services that they only listen on one control plane host, only on baremetal?

Ports are assumed to be used on all nodes in all clusters unless otherwise specified.

• The doc says we need to declare the ports on the pod spec, which we aren't doing. Is that something we need to do in the CBO?

- declare that port in their `Pod.Spec`

I mentioned that it's control-plane only; I think that's sufficient. You don't know which node it's going to be on, and it can move, so it's not like you can go ahead and reuse those ports on other hosts. For the purposes of this document these services own these ports on the control plane.

I agree that it might not be obvious to everyone that stuff that mentions baremetal only runs when the platform is baremetal IPI. Not sure how to fit that in the notes column without writing an essay :D

Yes. I added it to my PR already.
