Fix #74 Can't login when SuiteCRM 8 is behind a LoadBalancer

[chris001]

Description

When using the v8 application behind a load balancer, the requests come in as http, even when the application is installed with https enabled. This causes login failure.
This change causes the http request from the proxy to be rewritten as https so that the application's security requirement for login is satisfied. The application allows login only from https.

Motivation and Context

Login should be working now, when running v8 behind a http proxy or load balancer (e.g. Kubernetes, Helm Charts).
Bitnami should undo its deprecation of SuiteCRM v8 from the list of supported Helm Charts applications.

How To Test This

Install v8 application behind a http proxy or load balancer, without the changes.
Try to login. It should fail with a variety of error messages.
Apply the changes. Login should work fine.
