Refactored SecurityRequirement **breaking change**

The v3 model is wrong and out of sync with the spec. It's been corrected, so the v2 and v2 model for SecurityRequirement have been collapsed down into a base model., they are the same data structures. This has allowed me to delete the complexity of sharing two different models for the same structure, by unifying the model correctly. I am not sure why I decided to change the v3 model, oh well, its been corrected. Long live swagger!
