Show summary data as tree structure in explorer. (#8430)

* Show summary data vectors in project explorer for both summary cases and ensembles.
* Enable Drag to be able to drag'n'drop data vector into future summary plot
* Make sure tree is refreshed on reload/replace operations
* Provide case id and ensemble id in drag/drop object in addition to address
