Revert "stateful_update: Deprecate/Delete"

This reverts commit 48c2e8a369c07d0b4ee1eaa2eba1e4ae13ee0123.

Reason for revert: autoupdater in Autotest is suspected to still need this, and this may be causing increased provision failures.  Revert since it's just removing an otherwise presumed unused file.
