* Jaeger: Add service dependency graph support
Add support for visualizing Jaeger's service dependency graph via the
Jaeger data source. Per the discussion[1], this is done by proxying the
internal Jaeger HTTP API endpoint used by Jaeger's own UI for fetching
graph data, and transforming it into a format suitable for the node
graph panel in Grafana.
