Replace Log4J/SLF4J dependency with JUL

[jsync-swirlds]

We are currently referring to a SLF4J bridge to Log4J (for minio).
We wish to replace this with the JUL bridge and remove the Log4J dependency, if possible.

Why not use System.Logger as logger to remove dependency completely and still be fully extendable?

[jsync-swirlds]

In our code we do, but the minio SDK uses SLF4J.

[hendrikebbers]

So we only talk about test dependencies?

[jsync-swirlds]

Correct, the production code has no dependencies outside the JDK.
