Summary: Stack context: ``` Our tracing subscriber has 3 layers: - File logging - Scuba - Sqlite (usually off) Although the actual Scuba logging is done in a background thread and we are using a non-blocking file writer, we still have a good chunk of work that happens for events & spans. The solution to this, is to create a `UnifiedLayer` that just sends everything into a background worker, that then delivers all traces to each `Exporter` to handle. In this diff, we will create an initial `UnifiedLayer` and incrementally move each existing layer into an `Exporter`. To test correctness, we will run both the old and unified implementations for initializing telemetry on a variety of workloads, and ensure that both are producing the same results ``` In this diff we will create an `Exporter` meant to replace `file_layer` and update our correctness test to ensure that files produced by both the existing and the new implementation are the same Differential Revision: D87363775

Summary: We disallow methods relating to time to ensure that we use `hyperactor::clock`, but need to make an exception for this for telemetry because we would create a circular dependency if we tried to use `hyperactor::clock` Reviewed By: shayne-fletcher, dulinriley Differential Revision: D87664116
Summary: Each process only logs to monarch_executions once at the beginning of the execution so there is no need to add a scuba client that logs to this table into our tracing subscriber Reviewed By: vidhyav Differential Revision: D87664117
