Improve readability of UserDefinedName and PayloadDisplayName in Config Profile

Summary of the problem

I wanted to put in a quick request to see if we could get a few more user defined options to set the UserDefinedName and PayloadDisplayName in user.mobilconfig or alternatively set those variables automatically for better readability.

For example, I thought it would be a nice to allow a naming schema that helps identify hostname, city, country and IP address. For example:

[hostname] [Datacenter City] [Unicode Country Flag] [IP Address]

This will also help tremendously when someone has multiple VPNs that they're running at the same time.

I tested this on macOS and iOS and the Unicode Flag (i.e. an emoji) doesn't seem to break the config profile.
