Grafana Live Streaming Datasource Implementation

Inspired by the live-streaming talk at Grafanacon 2019, this is a living example of streaming within a datasource- including a reference server that streams random data. This will spawn a server at that this datasource reads data from. By default, the sever will stream data at 50ms, and the datasource plugin will throttle repaints to 100ms.
