/**
 * Profile owner provisioning sets up a separate profile on a device whose primary user is already
 * set up or being set up.
 *
 * <p>
 * The typical example is setting up a corporate profile that is controlled by their employer on a
 * users personal device to keep personal and work data separate.
 *
 * <p>
 * The activity handles the UI for managed profile provisioning and starts the
 * {@link ProfileOwnerProvisioningService}, which runs through the setup steps in an
 * async task.
