(Get the code!)
'phased-percentage' key is tied to a specific image in the index.json file. If that image number is a full upgrade and our winning candidate lands on that image, then we can clearly use the phased-percentage to decide whether we'll select that upgrade path, or pretend we're up-to-date.
However, if the image is a delta and it's not the end-point for the upgrade what do we do? I.e. a delta update flows through an image with a non-matching percentage.
I think ideally we would just ignore any phased-percentages for non-endpoint delta updates. Ideally, the server would guarantee that such mid-upgrade deltas never had a phased-percentage key.
Thoughts?
