s4: "findprovisionusnranges" helper

[Matthias Dieter Wallnöfer]

Hi ekacnet,

after looking at bug report #8504 
(https://bugzilla.samba.org/show_bug.cgi?id=8504) I stumbled over 
"scripting/bin/findprovisionusnranges" which acts as helper for several 
other python scripts ("provision", "upgradeprovision", "samba-tool 
dbcheck") but at the moment doesn't get installed.
To fix this for "samba-tool dbcheck" which should be runnable after 
installation we could patch like this: 
http://gitweb.samba.org/samba.git/?p=mdw/samba.git;a=commitdiff;h=937ad0021266b156c72d842d81447b2d322bff26 
or, as Jelmer proposed on the patch review, convert it to a python 
module. What's your opinion?

Cheers,
Matthias
