Release v1.3.0

This release brings the Reference Tools 5GMS Application Function in line with 3GPP TS 26.512 v17.4.0.

Major changes in this release:

The single media entry point is gone from the ContentHostingConfiguration and has been replaced by entry points per distribution configuration. This allows multiple entry points for the same media to be configured which enables the Application Function to offer the UE the media in different formats.
Addition of systemd unit files to assist in the deployment of the 5GMS Application Function as a system service.
Addition of msaf-configuration utility which will be used by the Systemd unit files to configure the AF once it's started.
A few bug fixes
