[Feature request] Device Model in .mobileconfig configuration

[ammnt]

Hello,

in continue of #1383 please add device model identification for clients in logs. This string is directly encrypted in base64 in endpoint URL:
<key>ServerURL</key>
<string>https://agh.stub.domain/dns-query/client-identifier-name/b64:QXBwbGUgaVBob25lMTMsNA</string>
</dict>

QXBwbGUgaVBob25lMTMsNA -> Apple iPhone13,4 -> iPhone 12 Pro Max

Please do not confuse this with the client identifier. That's the Apple device identifier. As I know, it doesn't work for DoT.

Thank you.
Cheers🤙
