Change options requirement testing so that it is performed on the base load_from_options method. This will mean it gets shared between all loading mechanisms. I removed the verify_auth function because it is a bit too specific to the OSC/OCC case. auth_type is not something that is part of keystoneauth. I also modified the exception as it should no longer take the plugin name as this would be knowledge any calling function has. OSC/OCC could use this function to implement a higher level error message, but I think it should be keystoneauth's responsibility to validate auth plugins and they should just offload the options.
