Clear Linux* Distro Factory 0.7.0 - Split Build from Release

This is rather a simple release but does require care from users in other to upgrade to v0.7.0.

Previously both build and release, were done by a pipeline called 'release'. To provide a better entry point for doing QA on a release candidate that may block a build from being published, the publishing step was factored out on its own pipeline (called 'release'). The bulk of the old 'release' pipeline was renamed to 'build', since that is what it does: it builds a release candidate.

Therefore, publishing is no longer triggered automatically upon success of a build. Users need to properly configure their jobs to do so.
