BZ#1159392 - Add HTTPS configuration for all applications with NGINX

This patch adds:
* Config settings for the location of the SSL
  certificate and key.
* Sets up a common certificate and key that all applications can use
  to access HA apps over HTTPS without having to set up an alias
  and adding an app specific cert/key
