machine424 97f3219157 test(discovery): add a Configs test showing that the custom unmarshalling/marshalling is broken.
This went under the radar because the utils are never called directly.

We usually marshall/unmarshal Configs as embeded in a struct using UnmarshalYAMLWithInlineConfigs/MarshalYAMLWithInlineConfigs
which bypasses Configs' custom UnmarshalYAML/MarshalYAML
