Applying the helium release patch for integration

This commit does 2 things:

 a.) this commit does 2 things:
     i.) moves the versions from -SNAPSHOT to -Helium for the release and
     ii.) removes the dependency on OpenDOVE which was not part of the Helium release and so produced no -Helium artifacts
 b.) the Helium release only built the integration-features and distribution-karaf modules
 c.) the patch that generated that the helium release code is included (integration.patch) and can be applied to the project tag bbc3ccecba9e8be646e618d26e0836c727015de1 to build the exact code
 d.) that code doesn't build because OpenDOVE was not part of the release and thus the build for that part fails
 e.) if you want to build that code, it must be built with mvn clean install -pl :features-integration,:distribution-karaf to only build the same code as in the release
