on a Salty Broker (an instance of saltyd). A valid HTTP method such as GET, PUT, POST, DELETE or HEAD
is provided as the first argument and a valid API endpoint path such as /api/v1/blob -- The 3rd argument
is optional and if supplifed must either be a path to a filename containing the payload of the request,
- for reading from stdin, or if omitted will read from stdin.

This is mostly useful in debugging and development of the Salty Broker API and Client.
