Ability to set the WSL1 and perhaps WSL2 process to a higher level than 8

Nobody has claimed this yet.

**Is your feature request related to a problem? Please describe.**
We are using WSL1 for running Industry Control Software on Windows Systems, using NodeJs and some unix specific tools, however we are having performance issues, due to the process priority of WSL.

We would like to be able to increase the WSL priority

**Describe the solution you'd like**
Ability to configure that I could start WSL as e.g. Priority 13, and then anything started in WSL would still be 8, but it would be possible to start with a higher priority, using the regular system commands in Node.js `os.setPriority()` Method
https://www.geeksforgeeks.org/node-js-os-setpriority-method/

**Describe alternatives you've considered**
Perhaps all of WSL should just run as 13 or whatever is specified in a configuration variable.

**Additional context**
This is from Node running under Windows, just to share the Process Priority Levels

We are using WSL1 since we appreciate that we have the same IP number as the machine, and we know that we could configure us out of this, but we haven't made the transition to WSL2 of this reason.

No repository files or tests are identified. Start by investigating how WSL1 and WSL2 process priorities are assigned, then compare the requested behavior with Node.js os.setPriority(). Done means establishing whether a configurable WSL launch priority can be supported and defining its behavior for processes started inside WSL.
