Problem: FlavorsResource.showMetadata() results in a 404 error because it is issuing an API call that does not exist since Flavors do not have metadata. Instead, they have “extra-specs”, key-value pairs that the Nova scheduler uses to launch Servers on Hosts that can supply the capabilities described by the flavor's extra-specs. Solution: Replace showMetaData() with showExtraSpecs(), use the correct “os-extra_specs” extended API path and add a new ExtraSpecs class to deserialize the API response to a Map<String, String>.

it is issuing an API call that does not exist since Flavors do not have
metadata. Instead, they have something quite similar, “extra-specs”, key-value pairs that the
Nova scheduler uses to launch Servers on Hosts that can supply the
