Example of setting up kitchen-google to work with service accounts

[kisoku]

Hi,

I'm trying to use kitchen-google via CI and would like to create a .kitchen.yml configuration that uses a service account.

Would it be possible to add an example to the documentation ?

Here's what I had to do to get this working today.

Created a service account, downloaded the generated keys in JSON format and placed them in .config/gcloud/application_default_credentials.json or wherever GOOGLE_APPLICATION_CREDENTIALS is pointing.

Created an ssh key pair for my service account and modified the transports section of .kitchen.yml to use the correct username and path to the private key
