* update daily CI to include cluster and sentinel tests
* update daily CI to run when creating a new release
* update release scripts to work on the new redis.io hosts
Sometimes Redis patch releases are released in a matter of weeks or days
one after the other. In order to have less release friction the idea is
to stop writing changelogs by hand, in order to also cover everything
interesting there is to say. Useless things can be deleted manually by
the changelog. Also this gives more credits to contributors since often
in the commit message involved people are cited even when they are not
the authors of the commit.
