[umbrella] Node utilisation chart per partition and resource type

Node utilisation is calculated based on a resource name. The bar chart can only show one resource. The optimal solution would be to allow selecting a resource to show in the bar chart via a drop down or show all resource types.

Also need to look at the placing of the chart: the dashboard shows data not linked to a partition we should consider moving the diagram to the nodes page which is partition based to provide a better view.

This is a major change of REST objects, endpoints etc
