Backward incompatible changes

In order to stay current with dependencies, and also refine our APIs we have introduced some backward incompatible changes in this release. Most of the changes are mechanical in nature (changing package names, changing GAV coordinates, etc) and apply mostly to Helidon SE. Please see the 2.0.0-M1 CHANGELOG for details.
