Associate simulation events with spans for better traceability

[dandelany]

Background

Simulations can emit simulation events when they are run. This happens automatically when activities are created, and the user can also add their own events to act as useful log messages or warnings. Thanks to the changes in NASA-AMMOS/aerie-ui#1236 these events will be visible in the UI to provide extra visibility into what's going on "under the hood" when a sim is run.

Per @mattdailis we should be able to associate these events with the spans/activities that create them, which would help users trace them to their source.

Requirements

• Add information to simulation events to reference their associated Spans
• Display the span info in the sim events table (Add simulation events table panel aerie-ui#1236)
• Ideally have UI which lets you link/scroll to the Span in question from the sim events table
