Handle docker image with missing labels #5

org.label-schema.memory-hint could not be present (example).

How do we handle such cases?

Answer with a 400 HTTP status code wit the error message This container image doesn't contain all the needed metadatas.
Something else?

label-schema had defined a key for the CPU in a draft but it comes across as being removed. The goal now is to check the presence of the key org.label.schema.cpu-hint. If one or both of those keys were missing, put default values (0.1 for cpus and 32 for memory).
