Since python2.6, python has a proper ternary construct "A if PRED else B". The older idiom "PRED and A or B" has a hidden trap - when A is itself false, the result is (unexpectedly) B. This change removes all cases of the older construct found using a trivial git grep " and .* or " - except one case in oslo common code (fixed in oslo upstream).
