Double nested Classes are not compatible with Java

[mmartin-paxos]

With the current Implementation, the plugin is not compatible with Java even though Gatling provides multiple compatibilities with Scala/Java/Kotlin. Therefore to make it Java compatible it is needed to apply a minor refactor at KafkaRequestBuilderBase.scala to remove the double nested class definition for
def replyTopic(outputTopic: Expression[String], headerIdentifier:Option[String] = None)
and
def requestTopic(rt: Expression[String]): RRInTopicStep = RRInTopicStep(rt)

I will propose a solution to this issue in a feature/branch

[jigarkhwar]

we are planning to add java/kotlin compatibility in this quarter

Good to know, we will be waiting for this feature.
Thanks!
