[one-users] update to 2.0.1 replaces oned.conf

[knawnd at gmail.com]

Hi!

I noticed that update from 2.0 to 2.0.1 (rpm was downloaded from 
http://dev.opennebula.org/attachments/download/270/opennebula-2.0.1-1.i386.rpm) 
replaced the existing /etc/one/oned.conf.

Is it expected behaviour? I guess it would be more referable way to keep 
the previous config instead of replacing by the new one coming from 
updated rpm package.

Nikolay.
