Multi-user support for PM2 daemon on Windows

[yastanotheruser]

What's going wrong?

Currently, PM2 lacks support for multiple users on Windows. This is due to the IPC pipe names being hardcoded in:

https://github.com/Unitech/pm2/blob/5e708459aca32903fd363230e24c37b3e38bb48d/paths.js#L82-L88

How could we reproduce this issue?

Run PM2 as two different users on Windows.

I faced this issue and later found out I needed to run PM2 from an admin elevated terminal. This solved the issue
