[feature] switch containers to wildcard jar import

[duncdrum]

Further align existdb/existdb with duncdrum/existdb

[adamretter]

What does this mean in practice?

[duncdrum]

drop the uber.jar change the CLASSPATH to use wildcards. duncdrum/existdb has been doing it since 01/2022

Okay... But why? What is the perceived advantage @duncdrum

We could introduce the more simple classloader to the main application too;
the configuration XML file with JAR references has been a pain in the past a few times.
And the build scripts are un-understandble large.
