Move to maven build tool

[morazow]

Situation

We are currently using sbt for building Scala projects. We would like to check if it is possible to migrate to maven based build so that we do not reimplement our build tools (code-crawler, project-keeper, and others).

• Migrated to maven build (compile, test, ittest)
• Coverage, style and linting plugins are migrated
• Releasing (possible cross versions releases) are possible
