merge: Add tests for interference and failures in Capelin

This pull request updates the Capelin experiments to test for interference and failure scenarios. 
This allows us to track regressions in these subsystems more easily.

* Clean up Bitbrains trace reader to enable re-use 
* Keep trace order after sampling
* Update Bitbrains trace tests
* Add support for reporting interfered work
* Add support for SimHost failure
* Add tests for interference and failures
