Norman Maurer 89866da252 Add CI job for JDK17 (#11584)
Motivation:

As JDK17 is really close to be released we should add a CI job for it to ensure netty works correctly when using it.

Modifications:

Add docker config and workflow config to run CI job for JDK17

Result:

Ensure netty works on JDK17 as well
