Problems with `--forks` feature: - Does not support dynamic restart (related: #268) - Does not support watchdog - First process is single point of failure - Per-instance configuration via environment variables is harder - Fixing this practically means re-implementing systemd or supervisord, which is obviously a bad idea. Related: #529 Task list: - [x] remove `-f` option and related forking code - [x] `worker.count` should also be removed - [ ] remove -f usage from all testing scripts, deckard, respdiff etc. - [ ] update our benchmakring docker image to be able to run multiple kresd instances without `-f`
