For the CentOS CI test results there might be no 'item' key at all in ResultsDB, so we have to modify the subject list field in the POST /decision API to accept
a list of dicts rather than a list of 'item' key , where each dict contains one or more key-value pairs of 'data' key in ResultsDB. Greenwave will then look
up results by passing these key-value pairs directly to the ResultsDB query.
