Remove Commons_release from Commons

Historically Commons has used the Commons release project to track usage statistics of Commons.

We can track usage statistics against the main Commons project as long as it has a release of some kind (even one that does not contained a packaged distribution) and the proper information in the feature module's info files. This is even easier to provide now that #779476: Remove commit restrictions for installation profiles is fixed.

Also, Commons_release unsets update status information for contributed projects included with Commons with has 2 negative effects:
- Site admins aren't notified of new versions of the contrib projects, including security releases
- Sites running Commons do not report usage data to the underyling contrib projects. For example: OG Features would appear to be running on ~98 sites, but in fact is a dependency for all Commons 2.x sites, of which there are several times that number.
