OPENIG-358 (CR-5060) Improve generated names for inline object declarations

Although the JSON pointer is sufficient to guarantee unicity of a name
within the scope of a heap, it makes it hard for reader to link that name
to the configuration object they provided.

This patch supports both improvements:
* if a `name` attribute is provided in the declaration, use it as-is
* if not, prepend the `type` attribute value to the pointer String to help identification

This patch also updates the logs samples provided in the documentation.

Thanks to Guillaume for pointing out what I'd missed.
