[Autotest,KVM-AUTOTEST,2/4] Make kvm_config.py to use internal/standard exeptions

One more thing: maybe we shouldn't test if the file exists and raise IOError ourselves --
python does this automatically anyway when we call open() for a file that doesn't exist.

Subject: Re: [Autotest] [KVM-AUTOTEST PATCH 2/4] Make kvm_config.py to use internal/standard exeptions

Looks fine to me.

BTW, I think debug_print() should be prefixed by a single underscore, not two.
A double underscore should be used only when name mangling is required -- at least that's what I understood from PEP 8.
Let me know what you think.

Thanks,
Michael

Instead of resorting to internal autotest exception types, use
either python standard exceptions or an internally defined
ConfigError exception.
