After a conversation with Dan, we are adjusting the classification label in the grouped by project api response. Relevant location in the code: https://github.com/project-koku/koku/blob/main/koku/api/report/queries.py#L624

We are going to remove the `default_project = True or False` piece stick to a consistent name of `classification` and default projects will have a specific one.

The following classifications should be defined for when we are grouped by project:

• default for the projects that are kube- or openshift-
•  category_<category_name> for the categories, so category_Platform for the Platform category
• unallocated for the Platform Unallocated and Worker Unallocated projects
• project for anything that does not fit any of the above criteria
