If the Graphite Web server is unreachable, all requests for frontend pages containing graphs hang until the backend HTTP request times out, resulting in a very poor UX. The Guzzle documentation states that the default behaviour is to wait indefinitely, however in our testing the cURL handler has an internal default of 30 seconds: https://docs.guzzlephp.org/en/stable/request-options.html#timeout This commit makes the HTTP request timeout configurable and sets a reasonable default of 10 seconds.
