Disabled MongoDB file preallocation

If enabled, MongoDB preallocate at least 2 2GB files on the
filesystem. It gives better insertion performances, but wastes
precious VM space. In the DemoVM context, we dont need optimized
insertion performances as MongoDB is only a storage backend for
operatinal data without any operational application connected to
feed it.
