api: show latest version of all branches

Not only show latest stable branches but the latest version for every
branch supported. Clients should figure out on their own if an upgrade
is required.

* Stable releases don't require an upgrade to the same stable release
* Release SNAPSHOTS can be upgraded to release SNAPSHOTS ,RCs or release
* SNAPSHOTS only upgrade to SNAPSHOTS
