setup log

Description of problem:
ascii check for ISO Domain name should be done immediately when defining domain name.

I was able to define 'ČÍNA' as domain name for ISO domain during engine-setup.
Nothing informed me that this name is not valid but in the end of engine-setup ascii check was done and failed because of this name and engine-setup did roll-back.

I would expect this check would be done immediately in time of defining the name and not too late when whole setup fails and then rollbacks. It's "useless" lose of time...

Version-Release number of selected component (if applicable):
rhevm-setup-3.3.1-0.47.el6ev.noarch

How reproducible:
100%

Steps to Reproduce:
1. define ISO domain with non-ascii chars during engine-setup
2. see where it fails
3.

Actual results:
fails too late, in the end of the whole setup

Expected results:
raise warning immediately to inform to define valid ascii name
