Improve performance of "DashboardController.getCollectionMonitorSummary()"-endpoint. 

Now, a single "getRepositoryAggregations"-call is made, which results in just one "DSM-aggregationhistory"-api-call. Previously, multiple api-calls where made, each requesting the whole "aggregationhistory"-data and then trimming it down to only a few results.
