how to: reduce build dependencies about akka-guide

[ignasi35]

Hi @patriknw, this is a rather specific how-to. Other how-to pages will be of use for users with their codebases but this looks too specific for people halfway through the tutorial. I'd rather not add this to the how-to section.

I don't understand what you mean?

what is "too specific"?

This is optional so I don't understand "halfway through the tutorial"?

An example: They create a microservice project that is not using Kafka. We include Kafka dependencies from the g8 template, but this how-to explains that the Kafka dependency can be removed.

I forgot about the .g8 template.
