nit: Class comment would be nice to explain what this is good for.

Done.

I was assuming that this is going to be the service that will host the write
path for device settings eventually (i.e. signing, then passing the signed blob
on the DeviceSettingsService). In that light, maybe we should name this
OwnerSettingsService already now?

Also, it would be great if there was a reference to the bug that has the
background on where we want to go with this (I think I saw one where we
discussed stuff?).
