log4j-tools and log4j-maven-shade-plugin-extensions

[Volkan Yazıcı <vo...@yazi.ci>]

*TL;DR*

I propose moving the `log4j-server` module of the `log4j-tools` project to
a PR, merging `log4j-maven-shade-plugin-extensions` PR, and releasing
`log4j-tools`. Objections?

*Long story*

Months months ago, I talked about onboarding the
maven-shaded-log4j-transformer
<https://github.com/edwgiz/maven-shaded-log4j-transformer> as an official
Log4j plugin. It is proven to be working and useful – we use it in the
`log4j-perf` module. In a nutshell, it makes the Log4j 2 plugin system work
when multi JARs get combined via shading. In succeeding discussions, we
decided to use the log4j-tools
<https://github.com/apache/logging-log4j-tools> project to host it. In the
meantime, I made the original author an offer he couldn't refuse and he
kindly landed a PR <https://github.com/apache/logging-log4j-tools/pull/2>.
Now... It is time to ship this transformer... but...

`log4j-tools` historically never had any releases, yet contains a
`log4j-server` module. The what and how of it can be found in the
repository. Given it was neither touched, nor released after several years,
I think it is in a stale state.
