Find new Gerrit releases

[chriscool]

It seems that we should try to do something about Gerrit releases as we often forget them, see: git/git.github.io#310

The easiest way is to fetch tags from the Gerrit Code Review repo (https://gerrit.googlesource.com/gerrit) or its GitHub mirror (https://github.com/GerritCodeReview/gerrit). What do you think?

The problem is that we also want a link that points if possible to release notes on a regular web page or otherwise on a mailing list archive page.

Let me ping the problem to the mailing list and we can get some proposals out of it :-)

There is something that seems to work in: 2ccb642
It would be better to have something in get_releases.py though.
