CVE-2019-12781: Incorrect HTTP detection with reverse-proxy connecting via HTTPS

When deployed behind a reverse-proxy connecting to Django via HTTPS, django.http.HttpRequest.scheme would incorrectly detect client requests made via HTTP as using HTTPS. This entails incorrect results for is_secure(), and build_absolute_uri(), and that HTTP requests would not be redirected to HTTPS in accordance with SECURE_SSL_REDIRECT.

HttpRequest.scheme now respects SECURE_PROXY_SSL_HEADER, if it is configured, and the appropriate header is set on the request, for both HTTP and HTTPS requests.

If you deploy Django behind a reverse-proxy that forwards HTTP requests, and that connects to Django via HTTPS, be sure to verify that your application correctly handles code paths relying on scheme, is_secure(), build_absolute_uri(), and SECURE_SSL_REDIRECT.
