FIX: Enabling Grafana testFramework for successful upgrades
Currently upgrading BigBang from version 1.8.0 > 1.9.0 does not work because the grafana.testFramework.enabled
binary got removed from chart/values.yaml and then added back and disabled in the latest version. The prometheus-operator is not able to reconcile this state but can be alleviated by explicitly enabling grafana.testFramework.enabled
.
