Cloudfront https proxy

[hierro1981]

If phpmyadmin is deployed on an http web server behind an AWS CloudFront distribution that support https, phpmyadmin warn the user about a possible "mismatch between HTTPS indicated on the server and client".

On the libraries/classes/config.php there are already some checks, on isHttps function, for different kind of proxy but there is no AWS specifi one.
Adding the following check on it should correct the behaviour:

        ...
	} elseif (strtolower(Core::getenv('HTTP_CLOUDFRONT_FORWARDED_PROTO')) == 'https') {
            $is_https = true;
        }
        ...

@hierro1981 can you please try fd2b172 before 4.9.3 is out ?

@williamdes modifing my 4.9.2 config.php with the changes of fd2b172 works and remove the warning
