fix: otel resiliency (#26857)

Improving the breadth of collected data, and ensuring that the collected
data is more likely to be successfully reported.

- Use `log` crate in more places
- Hook up `log` crate to otel
- Switch to process-wide otel processors
- Handle places that use `process::exit`

Also adds a more robust testing framework, with a deterministic tracing
setting.
