Add support for network latency

Description

It would be very useful to have the ability to test a process under high network latency conditions without the need of a MiTM / Proxy.

Details

I did a quick research on the JOB_OBJECT_NET_* constants, but I couldn't find anything related to latency...

So I'm not sure if this would be possible but I would appreciate an additional check / comment 🙏

Hi @kapsiR, thank you for the suggestion. Unfortunately, you are right. I did some research on job network limits, too, and the only one I found was the bandwidth limit. So I added the --bandwitdth option to procgov, which uses the JOBOBJECT_NET_RATE_CONTROL_INFORMATION structure underneath. I don't have plans to work on the latency feature in the foreseeable future as there is no API I could easily use. I will close this ticket then.

However, if you'd like to play with network packets, you may check the WinDivert project. They provide a network filter driver, which you may control from user mode. I remember there were even .NET wrappers for its API available.
