Update release script (its the exact setup for creating the 0.6-incubating release)
Set version of poms to 0.7-incubating-SNAPSHOT ; 0.6-incubating release tasks:

- quick check on the quickstarts / build instructions to match the latest release
- quickstart.sh scrips now point to the correct versions.
