  - reclass: Revert virt.nic to hardcoded eth{0,1}
    
    Salt's virtualization model for virt:nic:default does not use real
    interface names that are present on the node, but instead it defaults
    to using "ethX" notation, that name being only a convention inside
    Salt internals.
    
    Moreover, the 'salt.control.virt' reclass class (located in
    /srv/salt/reclass/classes/system/salt/control) already provides a
    defalt maping between "eth{0,1}" and "br{0,1}". Using anything
    different than "eth{0,1}" will lead to 2 extra (broken) mappings.
    
    Reverting the changes in "virt:nic" reclass fixes both the python
    exception recently introduced, as well as the broken defaults.
