  Delegate into transactional_update module

  The `transactional_update` module support the execution of functions inside a transaction, as support apply a state (via `apply`, `sls`, `single` or `highstate`).

  This execution module can be used to route some Salt modules and functions to be executed inside the transaction snapshot.

        - direct_call

  Or use the command line parameter:

      salt-call --module-executors='[transactional_update, direct_call]' test.version

  You can also schedule a reboot if needed:

      salt-call --module-executors='[transactional_update]' state.sls stuff activate_transaction=True

      # Replace the list of default functions that are delegated to
