Enable usage of kai binary in non-admin Windows use case

[dymurray]

Consider a user who is running on a secured corporate laptop. (Think of a user in a FSI or Public Sector).

Requirements:

• Windows OS
• User is NOT able to install additional runtimes, they are limited to only using the runtimes provided in their corporate image. We will assume this includes a JDK and an IDE
• User has limited permissions, is able to download, save, and open a compressed file (zip)
• User is NOT able to run a typical Windows installation process, i.e. not able to install libraries/files to privileged directories
• All dependencies must be contained within the zip file
• NO reliance on 3rd party utilities being present, i.e. we can not depend on a system 'grep', if we need a utility it must be bundled in the zip and must be able to run without requiring an official installation more than unzipping it.
• User is NOT able to launch a process that requires the need to open and listen on a port
