Consider building a TUI like dagger based on opentelemetry

Issue and related discussion copied from internal git instance
It did not occur to me before playing with dagger CI that the information we want to display in a UI is really just spans. A span is a tracing term used in microservices. They have a start time and end time and associated metadata (what is happening). Dagger leverages opentelemetry to output traces of this information and then they have a TUI built on top of it that allows for verbosity to be dynamic.

Note: an experiment for this is on the internal git instance, although our knowledge of OpenTelemetry has increased substantially since then so it's likely inefficient.
