Ben Nemec 69653318f4 Switch to oslo.log
The old oslo-incubator log module isn't maintained (and doesn't even
exist anymore), so we don't really want to be using it.  It appears
this was the only incubator module we were actually using, so this
allows us to remove all of the unmaintained incubator code.
