Amend GUI to work directly towards ACM runtime

Amend GUI to work directly towards ACM runtime

GUI proxies the URLs towards the ACM runtime server across CLAMP backend
because clamp-backend handles the certificates for HTTPS communication
and also handles AAF.

For now, the Policy GUI is being used for testing and demonstration
purposes only.

As AAF is disabled and we are using HTTP, the GUI can now work towards
the ACM runtime server port directly for test installations.
