Improve the archetypes (from a Maven perspective)

There are some things in the archetypes that could be improved:

• Remove finaleName (replace with context configuration)
  • The finaleName configuration is very often misunderstood by Maven users. It only changes the name of the file created in target/. The actual artifact in the local or remote repository isn't changed. So, if this settings isn't required I'd like it to be removed so that people are not confused.
• The directory names of the modules in the functional-tests archetype should be named according to their artifactId
  • Maven best-practice
• Cargo plugin configuration should be moved to pluginManagement
  • This will enable executing the cargo plugin from the command line with the same configuration (not only as bound to the lifecycle)
