Relax the WFCORE-2849 requirement

WFCORE-2849 fails ops against domain profile resources if the OSH tries to register a Stage.RUNTIME step. But we are still hitting cases where we have OSHs that try to do this (see WFLY-9281). Since those OSHs have worked for years without this causing major trouble, failing the op seems excessive.

Instead I would like to log a WARN an INFO, and have the problematic 'addStep' call simply return without adding the step.

Perhaps this could be a DEBUG, but really if an OSH is doing this it is a bug and I'd like to not hide that. A WARN OTOH seems too high, as this likely does not harm the end user and there is nothing they can do about it other than not invoking the op.
