DevOps YAML to install standalone exe

[danieljurek]

This is already done by some languages directly in their testing framework. This issue is to create an eng/common YAML like test-proxy-tool.yml which uses the standalone exe instead of the .NET SDK dependent tool.

Discussed in: #8373

@scbedd I assume you handled this with #8549

You're dead on the money Wes. Closing.
