Change method of adding scripts to setup

[yurem]

Right now in order to update script in setup we have to do base64 encode of script and replace it in script.ldif. It's not convenient, time consuming and can led to ldif import error.

We need to add method to setup which should process all py files in folder and sub-folders and prepares variables in base64 format based of content of files in this folder. This allows in scripts.ldif replace content of py files with python variable from dictionary.
