Undocumented input parameters

[Bilge]

The only documented input parameter is upload_url, but the example also specifies asset_path, asset_name and asset_content_type. Where do these come from and how can they possibly be valid if they don't exist as part of the action or the underlying API?

Furthermore, all of these undocumented input parameters (asset_path, asset_name, and asset_content_type) are required. If you don't specify them in the with clause, you get an error such as the following during the run:

##[error]Input required and not supplied: asset_content_type

So, it would be really good to document these parameters.

furthermore, asset_name should simply default to the name of the input file?
