Validation pem is being used as a fake client pem

At least document whatever is going on. Do we eventually allow to have real client keypair registration, since Goiardi has the power?

I need to upload cookbooks and need a valid pem for knife to be happy. We had two options at that point - run chef-client or do a knife client create to generate a client.pem or make use of the validation pem.
