Uploading the engine configuration from an engine element

The upload verb is present on each engine element, such as single_fw.

Example: the JSON description of an engine refers to the verb in the following way:
"link":
    [
        …
        {
            "href": "http://localhost:8082/7.1/elements/single_fw/1552/upload",
            "rel": "upload"
        },
        …
    ],
This verb can be found in each engine type. In this example, it is shown in a Single Engine. It presents a query parameter — a filter that can be uploaded on a specific policy (?filter=ThePolicyName).

This verb starts the upload on the specific engine and the specified policy. It returns a 200 HTTP response status code and a similar upload status description as for the policy upload.
