HydraConsole beyind a proxy

[gioppoluca]

Using the Hydra Console behind a proxy does not work there are 2 places where proxy information needs to be set to allow it to work:

1. proxylib _makeCurlRequest
   curl_setopt($curl_handle, CURLOPT_PROXY, "proxy.server.com:3128");
   curl_setopt($curl_handle, CURLOPT_HEADER, true);
   curl_setopt($curl_handle, CURLOPT_USERAGENT, $this->_requestUserAgent);
   curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, true);

2. FileGetContentsLoader.loadDocument
   $streamContextOptions = array(
   'method' => 'GET',
   'header' => "Accept: application/ld+json, application/json; q=0.9, /; q=0.1\r\n",
   'timeout' => Processor::REMOTE_TIMEOUT,
   'request_fulluri' => true,
   'proxy' => 'tcp://proxy.server.com:3128',
   );

With those two hacks it works; should be possible to set the proxy at AjaxProxy level and at JsonLD level
