AWS ENV vars not honored

[joegoggins]

It doesn't appear that AWS ENV vars are honored as described in README.
Even with the env vars set or by doing the following:

aws_access_key_id: <%= ENV['AWS_ACCESS_KEY'] %>
aws_secret_access_key: <%= ENV['AWS_SECRET_KEY'] %>
aws_ssh_key_id: <%= ENV['AWS_SSH_KEY_ID'] %>

I get this error:

-----> Starting Kitchen (v1.0.0.beta.3)
>>>>>> ------Exception-------

If you're still having this issue, could I ask that you upgrade Test Kitchen to at least 1.0.0.rc.1 and run kitchen list --debug to see what the resolved values for your keys are? Thank you!

Ohai! I've just tested your use case with the latest Test Kitchen and Kitchen EC2 driver and was unable to reproduce your error. If you are still encountering this error, please reopen this issue and include the output of kitchen diagnose.

Thanks for looking into it, will let you know if I have troubles after upgrading.
