We have a HttpCheck that can check rules by calling a remote server. However currently it just supports "http://" and not "https://". In this patch, we add a HttpsCheck so we can support "https://" urls as well. In addition to ensure security, we add options to: * Specify a ca cert to validate the server * Specify cert/key to allow server to validate the client Another quirk was that currently the payload is being sent using 'application/x-www-form-urlencoded' as the content-type. We add another option to send the payload as 'application/json'. Add this same support to the HttpCheck as well. Change-Id: Ic9c5249555fb45010a92432a504c84ad3fbb9ea1
