Grafana dashboard doesn't handle wildcard scaledObject variables properly for some graphs

[alexkuretz]

Report

All 4 of the ScaleTarget graphs won't render graphs if more than one scaledObject exists in the namespace and the "All" option is selected for the variable. This is due to incorrect wildcard matching definition in the graphs for scaledObject variable.

Expected Behavior

Expect graphs to display metrics for all scaledObjects

Actual Behavior

No metrics are displayed

Steps to Reproduce the Problem

1. View a namespace that has multiple scaledObjects
2. Select the "All" value for scaledObject variable
