Chef-solo provisioning on Windows

_This issue was originally opened by @Chan9390 as hashicorp/packer#5220. It was migrated here as a result of the [Packer plugin split](https://github.com/hashicorp/packer/issues/8610#issuecomment-770034737). The original body of the issue is below._

**Chef solo isn't installing on Windows Server 2008 R2**. Other provisioning like shell and powershell are working fine, but when it comes to chef-solo provisioning, the **inbuilt installation script gets stuck**.

I tried the following workarounds:
- Overriding the inbuilt command with `install_command`. Doesnt work
- Have a shell provisioning with installation command. Doesnt work
- Have a powershell provisioning with installation command. Doesnt work

The guest VM is *Windows Server 2008 R2*. It has dotNet 4.5 and Windows Management Framework 5.0 installed (Powershell v5 is present).

- Packer version : Tested with 1.0.0 and 1.0.3
- Host platform : Ubuntu 16.04
- End output from logs:
