Add textual server setup steps for [#83941800]

Created both a .md and .pdf for easy viewing both online in GitHub
(.md) and offline (.pdf). Both types (and GitHub) support embedded images,
but I don't see any reason to walk through the system installation since
all configuration was done afterwards.

I created the .pdf from the .md with `pandoc -f markdown -o Server_Setup.pdf Server_Setup.md`.
On Debian and Ubuntu, pandoc is part of the `docutils` package. `pandoc` is
written in Haskell, and can be installed on Windows,Linux, and Mac from
 http://www.johnmacfarlane.net/pandoc/

TODO: Add any server-side steps for Visual Studio pushing to server.
Add pandoc instructions to README
