// Checks whether the installed web app associated with a given WebContents has
// out of date manifest data and what to update it to.
//
// High level procedure for this command:
// - Download new manifest data from site including external resources (such as
//   icon bitmaps).
// - Load existing manifest data from disk including external resources.
// - Diff manifest data.
// - Resolve any changes to app identity by confirming the change with the user,
//   silently allowing them, or reverting them.
// - Return back to the caller to schedule applying the changes back to disk.
