// state from the DMServer.
//
// The operation is aborted with state kNoEnrollment:
// * when device ownership is taken or unknown,
// * when RLZ brand code or serial number are missing
// All these values are retrieved using StatisticsProvider, which can be faked
// using `FakeStatisticsProvider` in tests.
//
// Additionally, the operation can be aborted with state kConnectionError:
// * when system clock failed to synchronize, or
// * server-backed state keys could not be retrieved.
//
// The operation will be concluded by calling `report_result` with the retrieved
// enrollment state or error. In case we retrieved state or determined lack
// thereof, additional details are stored as a dictionary under key
// `prefs::kServerBackedDeviceState` in `local_state`, which can contain entries
// with the following keys and values:
// * kDeviceStateMode:
// * kNoEnrollment,
// * kEnrollment, or
// * kDisabled;
// * kDeviceStateManagementDomain:
// * domain name or email address of the device owner;
// * kDeviceStateDisabledMessage:
// * message shown to the user in case the device is disabled;
// * kDeviceStateLicenseType:
// * empty string,
