[jdk11u-dev] RFR: 8297798: Timeout with DTLSOverDatagram test template [v3]

[Goetz Lindenmaier]

> I backport this to streamline testing based on the change in 17.
> 
> I had to resolve DTLSOverDatagram because the code in 11 uses classes, where the code in 17 uses records.
> The added code is identical in 11 and 17.
> 
> Tests pass.
