Grafana Dashboard: update to React components

[michalcukierman]

Graph (Angular based) s deprecated in the new versions of Grafana.
In order to automatically migrate to Time Series (React) dashboards the following steps are required:

1. Start Grafana in the development mode
2. append &__feature.autoMigrateOldPanels=true parameter to the URL. I.e.: http://localhost:3000/d/sWPi0L-mk/pulsar-messaging?orgId=1&refresh=1m&__feature.autoMigrateOldPanels=true
3. The dashboard can now be exported / incorporated into the codebase
