Overview of the Feature Request
For the SPA Collection Page, we need to show counts of the files, datasets, and collections (dataverses) in the results. To support this, we need to add a section to the API response, to contain the counts.
If preferred, we can make this behavior optional by adding a boolean show_type_counts parameter.
For example:

total_count_per_object_type: {
  collection: 3,
  dataset: 10,
  file: 75
}

What kind of user is the feature intended for?
(Example users roles: API User, Curator, Depositor, Guest, Superuser, Sysadmin)
