v9.0.0-alpha.2

Changes from 9.0.0-alpha.1:

• Rather than fully dropping the body parameter, each HTTP request type includes optional body and querystring parameters that will add any provided values to the body and querystring, respectively. They have permissive { [key: string]: any } types (basically Record<string, any>), except they do not allow any of properties that should been in the root of the object.
