Gradle plugin: Rewrite in kotlin

[Isammoc]

As kotlin is now the standard for plugin for gradle, we should rewrite our plugin.

Pros:

• will naturally solve issue with kotlin gradle configuration Gradle: Can't configure gatling section when using build.gradle.kts  #4337
• will use a typed language (more close to scala we know how to use)

Cons:

• we don't know kotlin either
• will have to dig in gradle documentation
• time consuming

Requirements:

• Current user groovy gradle configuration should still work (except for the plugin version itself, obviously)

[Isammoc]

I personally am in favor of a complete rewrite to follow the best practice of kotlin plugin for gradle. (ie, I don't advise to translate from our current groovy implementation)

If we decide to go this way, it's paramount that the existing groovy configuration keeps on working, or at least that the change is minimal.

Agree! Perhaps avoid to hard set the gatling version but let the user decide? (as in maven plugin?)

Perhaps avoid to hard set the gatling version

It's not hard set, it's a default value.

Closing as there's no plan for this any time soon.
