Agent forwarding doesn't work in 'kitchen converge' on windows.

[PurityControl]

I have the following set in my .kitchen.yml file:

transport:
  forward_agent: true

This works perfectly on my mac and I can forward ssh keys to the vm in order to clone a github repo.

When I am on windows. The keys forward when I use kitchen login but not when I use kitchen converge

When using kitchen login, I can type ssh-add -l and I can see my keys. This shows me that my set up is working on windows and my keys are available for forwarding to the machine.

However if I log ssh-add -l to the console when running a kitchen converge some keys are shown in the console but none of them are forwarded keys.

Is this a bug or am I doing something wrong?
