Add the __contains__ function to the rtevalCfgSection class  to make "in"
function correctly.

For example in cyclictest.py, self.__cfg is not a dictionary, it is an
instance of the rtevalCfgSection class, therefore
key in self.__cfg
does not work as expected. In order to make sure this is fixed
everywhere, instead of comparing to self.__cfg.keys() everywhere this is
used, implement the __contains__ function so that "in" works as
expected.

This bug was introduced by the commit fd3b732f714d ("rteval: 2to3
transformations")
