Wiping and relinquishing org-owned devices

Add the following functionality, on devices with a managed profile
created during provisionining (and as such, considered
organization-owned):

* Let the Profile Owner relinquish a device by calling
  DevicePolicyManager.wipeData. The device then transitions
  to a fully-personal device.
* Let the Profile Owner wipe the entire device by calling
  wipeData on the parent profile DevicePolicyManager instance.
