Update to use fluo-parent POM and groupIds (#6)

* Update license headers
* Fix RAT checks
* Apply formatter from parent POM
* Build all examples as a multi-module project
* Fix checkstyle and modernizer warnings
* Fix a few findbugs warnings (but not all... run with -Dfindbugs.skip)
* Use org.apache.fluo groupIds instead of old groupIds
* Update gitignore files

Some tests are still failing, but seems like an unrelated issue.
