This change is coming in Epoxy, not Caracal, and I don't think we need the warning anyway. prometheus_blackbox_exporter_endpoints has been removed from the master branch already, so when we merge stackhpc/2025.1 to do the upgrades, it'll get removed automatically

Though it won't be removed from a kolla/globals.yml inside an environment.

@technowhizz can you update this to target stackhpc/master and mention kolla/globals.yml inside an environment specifically?

[Alex-Welsh]

@technowhizz I'd like to get this wrapped up soon since the epoxy release isn't far away. Can you respond to the comments & resolve the merge conflict?

[Alex-Welsh]

@technowhizz I've added a suggestion, could you review please?
