Tests using ProcessTools.executeProcess gets the following output written to stdout:
[2023-11-24T09:58:16.797540608Z] Gathering output for process 2517117
[2023-11-24T09:58:23.070781345Z] Waiting for completion for process 2517117
[2023-11-24T09:58:23.071045055Z] Waiting for completion finished for process 2517117

This might be good for some use cases and debugging, but some tests spawns a large number of processes and for those this output fills up the log files.

I propose that we add a way to turn of this output for tests where we find this output to be too noisy.
