Description
Currently the KpiService, calculates the values of every individual kpi whenever a the endpoint is being invoke. Since now in ES we have a new field called "lastKpiEvaluationResult" in the ProcessOverviewIndex we can simply do a look up there and fetch the last kpi value.
Edge Cases
We need to find a solution for what happens whenever we create a new report  as set it as a kpi, which doesnt exist in ES yet, as this will cause the endpoint not to return it until the next interval
AT:
- The KpiService fetched the values from ES for the report KPIs
- The KpiService inserts a kpi value to ES in case it doesnt exist there
