s4: Improve updateprovision
* Define a simple upgrade process mode (module storage change, file name change, copy of new file)
* Move the schema, configuration and current object upgrade into full upgrade mode
* Added the --full switch to select the full upgrade mode, and made simple upgrade mode the default
* Make updateprovision works without any switch (update the provision in the default location)
* Cleanup the messages
* Create the reference provision in a subdirectory of the updated provision
