Call middleware in an actual reasonable order
Begin attempt to sync folders into local zones

- LZ zone configuration can be rewritten to configure
  global synced folders in /zones/zonename

  middleware long before it's possible to do any actual
  configuration in a VM
- we have to re-run the builtin Vagrant middleware to
  ensure that changes to synced folder configuration is
  actually used
