Fix integration tests

- switched to configuration layout mandated by v2
- added `mage test` target that will run both unit and integration
  tests
- switched CI runs from just running unit tests to running all tests
- Skipped integration tests that require docker to run logstash or
  kafka, support for doing that is finalized in magefile.
- updated example config file

Closes elastic#244
