Remove Auto generated Argo code

[neildsouth]

Code in ArgoGeneratedCocde.cs has been generated from the Argo swagger, but the /log endpoint produces malformed Json, this has lead to the file being changed manually, not an ideal situation.

The code need implementing from scratch to include only the endpoints used and so then be customized to get around any issues

The generated code is being used by the Argo plugin for simple API calls; it does not support streaming APIs such as streaming logs. For complex data structures, it is recommended to use HttpClient directly.
