To add a new data-source to Central grafana running on CI/tools cluster,
add a entry in the Map global variable a the entry should be <cluster-id>:<teleport-app-name> , eg if I have a prometheus datasource in fennel-dev cluster and the prometheus app is named as fennel-dev-prometheus then the entry looks like
fennel-dev:fennel-dev-prometheus
Run pulumi up in the launchpad/ci project
