Performance measurement

[BacLuc]

The performance measurement part of

• Performance tests + switch to worker mode #6021

Start with performance tests for the api, that we can verify possible performance improvements.

Currently, the tool https://grafana.com/docs/k6 is used.

The output json is not meant as a benchmark.
Because the time is dependent on the instance (and network between and many other factors),
the output.json is not meant as a global reference, but as a relative reference.

If you have a place where you want to improve the performance,
first: run the performance tests against the instance.
then apply your change

• Analyse changes in the performance between php-fpm setup and frankenphp in prod #5692
