Description

This PR reduces code provenance overhead by:

  1. Generating code provenance metadata once and reusing it across processes that run with the same Python version, ddtrace versino, and installed dependency environment.
  2. Coordinating cache generation with a non-blocking path so contending processes return quickly instead of waiting, then retry on later uploads. It's possible to not have code provenance on first few uploads.
  3. Marking code provenance initialized only when a non-empty payload is actually set, ensuring skipped attempts can recover and use cached data later.

Testing

Added a microbenchmark where we fork 10 workers sequentially each calling CodeProvenance.json_str_to_export(). Prior to this PR, each worker would build the json file reading all package files. With this PR, only the first worker would do so and the following workers would read from /tmp file cache.
