Edits a Project via "diffs" from a configuration file ala execute_project_config_diff(). Runs in the calling
thread and therefore blocks. POST form fields:
- request.data (required) must have a 'project_config' field containing a dict valid for
execute_project_config_diff(). NB: this is different from other API args in this file in that it takes all
required information as data, whereas others take their main data as a file in request.FILES, plus some
additional data in request.data.
