064265b0b9 (crawler) Move content type/charset sniffing to a separate microlibrary 
This functionality needs to be accessed by the WarcSideloader, which is in the converter.  The resultant microlibrary is tiny, but I think in this case it's justifiable.

09917837d0 (process) Ensure construction exceptions are logged 
Wrapping these exceptions in a try-catch and logging them with slf4j will ensure they end up in the process logs.

The way it worked using the default exception handler, they'd print on console (which nothing captures!), leading to a very annoying debugging experience.

4baf9527d7 (*) WIP Control GUI redesign, executor-service, multi-node mq 
This turned out to be very difficult to do in small isolated steps.

* Design overhaul of the control gui using bootstrap
* Move the actors out of control-service into to a new executor-service, that can be run on multiple nodes
* Add node-affinity to message queue

dbe9235f3a (*) Upgrade to JDK21 with preview enabled. 
... also move some common configuration into the root build.gradle-file.

Support for JDK21 in lombok is a bit sketchy at the moment, but it seems to work.  This upgrade is kind of important as the new index construction really benefits from Arena based lifecycle control over off-heap memory.
