Message:

The protoGENI OS version lurched forward. This code removes the hacky stuff
used to support the old version and attempts to insure that a useful OSversion
is always used - it is possible to get the old OS randomly at this time as
well.

The hacks to support an ancient OS version don't work on a modern version and
vice versa, so we moved forward to teh modern version.

fedkit updates are also required.
