Do we need demo_gradle module?

[decebals]

I prefer to eliminate demo_gradle module, to "merge" this module (build scripts and the kotlin part) with demo module.
The code in demo_gradle is redundant in my opinion.

I don't use Gradle in my project and from this reason it's hard for me to maintain it (I admit that I don't know to much about Gradle).

@decebals I started using PF4J a couple of months ago and I am using Gradle, the demo was a big help for me.
I opened #177 to fix the demo and update PF4J to the latest version.
Please have a look.
(We can place it inside the demo folder)

Thanks for your contribution!
I don't realize yet if it's better to move the gradle scripts in demo directory and to remove demo_gradle.

I'd definitely vote for having demo/maven and demo/gradle.
