Open Stack

For a few months, some project core teams (including Nova's) have
been running with an ACL granting access to the "rebase" button in
Gerrit for all the projects they manage, a permission usually only
exposed to the "owner" of an individual change. This has been
generally useful for them, especially when someone updates a commit
message via the Gerrit WebUI and there are changes depending on that
one which then show as outdated. So far they've seen no real
drawbacks, and since it's already possible for any Gerrit user to
locally rebase and push that to a change as an updated patchset
anyway we've deemed it generally safe to go ahead and expose that
button to everyone.

If you encounter any unexpected issues you think might be related to
this behavior change, please let me or someone else in the Infra
team know about it. Thanks!
