Please allow additional visualization plugins to be installed

[rsheldon-ansira]

There are a lot of visualization plugins available for grafana, and AMG provide only a few of them. I understand that you want to provide a curated set of functionality, but the UI plugins run on the client side, so I an admin installs a plugin that has issues, that's on them.

For example, some of the ones I think are useful:

• Treemap Panel - https://grafana.com/grafana/plugins/marcusolsson-treemap-panel/
• Polystat Panel - https://grafana.com/grafana/plugins/grafana-polystat-panel/
• Bubble Chart - https://grafana.com/grafana/plugins/digrich-bubblechart-panel/
• https://grafana.com/grafana/plugins/jdbranham-diagram-panel/
