-// The consumer management service handles several things:
-//
-// 1. The consumer management status: The consumer management status is an enum
-//    indicating if the device is consumer-managed and if enrollment or un-
-//    enrollment is in progress. The service can be observed and the observers
-//    will be notified when the status is changed. Note that the observers may
-//    be notified even when the status is NOT changed. The observers need to
-//    check the status upon receiving the notification.
-//
-// 2. The consumer management stage: The consumer management stage is a value
-//    indicating the enrollment or the unenrollment process, stored in local
-//    state to pass the information across reboots and between components,
-//    including settings page, sign-in screen, and user notification.
-//
-// 3. Boot lockbox owner ID: Unlike the owner ID in CrosSettings, the owner ID
-//    stored in the boot lockbox can only be modified after reboot and before
-//    the first session starts. It is guaranteed that if the device is consumer
-//    managed, the owner ID in the boot lockbox will be available, but not the
-//    other way.
