Redirect all HTTP request to HTTPS for Enforce UI (Tomcat)

When a user enters the URL for the Enforce UI as a non-secure HTTP request (i.e.  http://localhost), an error page is displayed.

Unable to connect / This page can't be displayed.

The Enforce Console's tomcat webserver is configured to only accept HTTPS requests.  Any non-secure HTTP request will not be redirected.  By default the tomcat webserver is not configured to redirect HTTP requests to HTTPS.
