[et-mgmt-tools] OS type detection in virt-install/virt-manager

[Alexander Todorov]

Hello,
I was looking at the recent code in OSDistro.py
Can we switch to using the new .treeinfo file and the information there 
instead of the current if hasFile() mechanism?
The .treeinfo provides with all the information needed to detect the 
family type (Fedora, RHEL, CentOS ???) and boot images location.
Also improve the acquire$FILE functions with that information.

In case this is not found then we may fall back to the current code.

The reason I'm requesting this: in newer Fedora repos the packages dir 
is simply called "Packages" but not "Fedora" and wrt remixing tools it 
may be called with any name I think. OSDistro.py uses the presence of 
fedora.css in the repo to decide on a Fedora distribution. This file 
is not essential to the install process and may be missing in some repos.

What do you think?

Thanks,
Alexander.
