Extract webserver metrics into a separate class to avoid passing it into every API call. Change the display to requests per hour rather than just last request time. Add SSE and telnet client connected count.

     * **Breaking change:** The "add spot" API has changed to enable future support for upstream submission to the spotting services associated with various SIGs. Instead of just posting the spot object itself as the JSON content of the POST, this has moved into a `spot` object within the structure. A new `handling` object alongside it contains the `submit_upstream`, `upstream_provider`, `upstream_credentials`, and `captcha_token` fields which control the server handling of the spot.
