Any suggestions on how we can eliminate the need for this enum as well as
UpgradeNotificationAnnoyanceLevel ?

You could create a shared header somewhere in //components, but I don't see a
good place for it. The cure might be worse than the disease.

You could static_assert something in system_tray_delegate_utils.cc about the
enums matching if you're worried about them drifting apart.

Sorry, no great thoughts.
