Context:
See parent ticket. We need to add the FlowNode Start/EndDate filter on instance level as well. which filters where specific flowNodes have been started/ended on a specific date.
Structure: see follow up notes on confluence
Example (fixed date):
[{
    "type": "flowNodeStartDate" // or "flowNodeEndDate"
    "filterLevel": "instance", 
    "appliedTo": ["3fhi5r8ri83", ...] //  or ["all"]
    "data": 
		{ 
                  "flowNodeIds" :  ["userTask1", ...], // or null for viewLevel
		  "type" : "fixed", // fixed, rolling or relative filter data fields here
		  "start": "2017-11-11T11:11:11", 
		  "end" : "2017-11-11T11:11:11", 
		  "includeUndefined": true // optional
		  "excludeUndefined": false  // optional
		}
}, ...]
Reference for rolling and relative date data here
AT:
- FlowNode Start/EndDate also works on instanceLevel with a FlowNodeId selection
- Filter definition is added to Confluence
