Hi

I appreciate that it is a useful feature for you, but people rely on stable
branches being stable. This is a reasonably big patch (163) for a back port.
So I understand Zane's -1. That said, it is contained within ceilometer
alarm resource and the code now matches master. And the feature has been in
ceilometer for
ages.

I am OK with this going in, if stable branch folk are OK with it. (I'll put
a +1 on the review).
