Split performance profile job in two
...
... one that runs hourly and uploads to bigquery (for regression
detection)
... and one that will run daily and not upload to bigquery (for
flamegraph generation)

- More robustly run processes in the background
- Detect and use pypy if available
- Add a --latency_profile flag to control whether to run the latency profiling stuff

Lower latency profiling
...
Current latency profiles have their tails dominated by writing latency
logs, which is hugely undesirable.
Now when a thread log fills up, push it to a background thread to write
to disk. At shutdown, wait for all latency traces to be flushed.
