WIP - Parse Devfiles without flattening

When flattening, the Devfile parser seems to
set the default values for unset fields (like deployByDefault or autoBuild).
This makes it hard to determine cases where the component needs to be applied
automatically (e.g., deployByDefault not set and component not referenced by any Apply commands).

However, this also creates other issues when handling child Devfiles with Parents.

So needs to be discussed..
