Closes https://github.com/PostgREST/postgrest/issues/4107. Adds two python scripts: - monitor_pid.py: monitors the postgrest process each second until it exits, then outputs a csv with the results. The nix wrappers use the `loadtest` dir for the output. - merge_monitor_result.py: receives a list of csvs and merges them into a single markdown table. The nix wrappers use the `loadtest/*.csv` files for the input. The nix `postgrest-with-pgrst` and `postgrest-loadtest-report` commands use these scripts to add monitoring for `postgrest-loadtest` and `postgrest-loadtest-against`.
