Adds PSU Install Option to Environment

[JPRuskin]

Description Of Changes

Adds Start-C4bPsuSetup.ps1 to the install scripts available in the root of the repository.

Motivation and Context

We have a lot of excellent ideas that we can implement by helping customers utilize PowerShell Universal. We need to have a method for installing everything in that case.

Testing

1. Download repository
2. Comment out Jenkins install in initialize script
3. Run through init script
4. Manually trigger Start-C4bPsuSetup.ps1 with any args (e.g. thumbprint)
