[windows] convert IPC to named pipes.

[derekwbrown]

First commit: change process agent <-> system probe communication to use named pipes.

Motivation

Change ipc transport to named pipes instead of localhost tcp connections. Prevents port collisions.

Additional Notes

Possible Drawbacks / Trade-offs

Due to switch to named pipes, can no longer use curl/wget/iwr to connect to system probe endpoint for debugging.

Describe how to test/QA your changes

• install build, enable npm and/or usm
• ensure process agent can still communicate with system probe
  • no errors in logs indicating problem at startup
  • logs indicate successful retrieval of connection informatoin.

Is there a tool that does support named pipes?

Is there a tool that does support named pipes?

I've been googling around and haven't found anything with the built-in tools. It would be straightforward enough to write our own python and/or powershell and/or go tool.
