Summary: This adds debug commands for ActivityRecorder: ``` eden debug start_recording --output-dir <DIR> * stdout: the id of the profile eden debug stop_recording --unique <ID> * stdout: the output file path ``` Users can record multiple profiles concurrently. Each profile is identified by the timestamp when it started. Reviewed By: genevievehelsel Differential Revision: D29666359 fbshipit-source-id: 487ca67de77378a8141bc4ac46b9abd1375ffd23
