Use real types to parse labels

We were using `yaml.Unmarshal` on basic types or inline structs. This
was not efficient and not clear to defined what we expect in labels.
We now use types to unmarshal the labels.

Only the `values` label is, at this time, parsed by GetValuesFromLabel
because this `utils` function is clearly a special case.
