[BAHIR-18] Configure examples as maven test sources

This PR configure examples as maven test resources to be
recognized by maven builds. This acomplish the following :

- The examples get compiled
- IDEs like IntelliJ or Eclipse recognize the
  <module>/examples/src/[java|scala] as source folders
- Keep the examples along with their additional dependencies
  excluded from the generated binaries

Closes #2
