Consider adding support for json.env files to Test Framework

[JoshLove-msft]

Using the -OutFile flag of the New-TestResources.ps1 script, will cause the script to create a test-resources.json.env file next to the test-resources.json file that contains the environment settings in an encrypted format.

The .NET Test Framework reads this file so that users don't need to manually set environment variables after running New-TestResources locally.

It would be great if the Python Test Framework could support this feature as well so that we can use this as a cross language selling point of the Track 2 Test Frameworks.
