 * CTS verifier test for BYOD managed provisioning flow.
 * This activity is responsible for starting the managed provisioning flow and verify the outcome of provisioning.
 * It performs the following verifications:
 *   Full disk encryption is enabled.
 *   Profile owner is correctly installed.
 *   Profile owner shows up in the Settings app.
 *   Badged work apps show up in launcher.
 * The first two verifications are performed automatically, by interacting with profile owner using
 * cross-profile intents, while the last two are carried out manually by the user.
