Adding windows stack support

[dbathgate]

Overview

Cloud Foundry has support for running Windows workloads. There is the ability to have buildpacks that support both the cflinuxfs* and windows, but the compatibility for both needs to be maintained by the buildpack owner.

Proposed Solution

• Buildpacks that support Windows need to have an equivalent Windows Batch script for compile and supply (supply.bat, compile.bat)
• The 0001_retrieve-secrets.sh for exporting secrets as environment variables would need to be ported to a Windows Batch script as well
• The Go executable would also need to be compile for the Windows OS

Additional Considerations

• The Windows supported buildpack could either be in this repository and an entirely new repository
• Developers could use Conjur SDK's to retrieve secrets programmatically rather than relying on the buildpack. The Windows buildpack primarily serves .NET Framework users so there would need to be a .NET framework SDK.

Proof-of-Concept

• I have created a POC demonstrating how this buildpack would work on a Windows stack: Commit here
• This POC is functional, but still needs some enhancements.
• We may have a need for this in the future and I am looking to assess the possibility of this becoming a supported feature of this buildpack.
