Feature/464 permission admin view slow

[danielmursa-dev]

Fixes #464

An internal administration endpoint admin/core/objecttype/<objecttype_id>/_versions/ was created to retrieve all versions related to the objecttype.

Then the FE part was modified, so that each time an objecttype is modifie/selected, it call a new request to the endpoint.

I was thinking of the following to make it possible to fetch the fields via the frontend (such that the form doesn't have to be saved to fetch them):

• make an endpoint on the admin (that requires admin authentication) that performs the request for a specific object_type_id to retrieve the data_fields (e.g. /admin/objecttypes/<id>). That way we don't have to expose the token to the frontend and we only need to pass the id to the frontend
• in react, call this new endpoint for the currently selected objecttype and display the result

@annashamray what do you think about this?

Looks good overall, some minor questions/remarks

[annashamray]

One thing I've noticed now, but it's been implemented like this since the beginning:

The state of selected fields is not tracked:
If you change the objecttype in the dropdown and then change it back, the fields previous will not be selected, even if they are saved in the DB

It's been like this probably forever, so could you please create an issue to fix it?
No need to fix it in this PR, but some cleanup would be nice

[annashamray]

Please create an issue for keeping track of selected fields after changing the objecttype

Some minor comments about the tests, looks good otherwise
