- Show the opt-in text
- Show the account picker if user presses 'enable sync'. Previously
  we disabled the sync pref which was confusing.
- Remove the debug tags from some prefs; and improve messaging overall

General rules;
- sync is turned ON : user checks 'enable sync' pref AND
  accepts the opt-in AND chooses an account
- sync is turned OFF: when user signs out

Change-Id: I5e91a7fd0efdc16e140a91fab6300bd8ba9cd6c7

- Adds a preference for enabling sync, which controls the sync behavior
- Make the ProductionFlags depend on appropriate flags to guarantee that
  we don't mess things when flipping some flags

  thereby controlling the policy and when this entry shows up in
  system settings.
