mv_machine_learning: drop parsing dependency from object detection 3d

[Issue type] : code refactoring

Drop the configuration and meta file parsing dependency from ObjectDetection3d
class.

Until now, the concrete class of each task group got the task group
configuration information from its own configuration file, and also
included a MetaParser class object to get the tensor information,
which is corresponding to a given model file.

However, these dependencies led code smell, divergent change[1] even though
the concrete class has no any dependency from parsing the configuration and
meta files - needed only information after parsed.

As a first refactoring work, this patch extracts parsing portion from
ObjectDetection3d class and introduces as a new class, ObjectDetection3dConfig
class.

With this, adapter classes of the object detection 3d task group will parse
the configuration and meta files before creating ObjectDetection3d class.
And then it will create ObjectDetection3d class with needed information.
As a result, we could manage the ObjectDetection3d class without any
dependency on parsing work.
