Fix undefined vars in cnos module_utils

Fixing undefined vars across the codebase so that we can have pylint
catch them on every commit.

Some of the changes to this module_utils file are Python3 related => The
identifiers exist on python2 but not on Python3.  The changes should be
portable to both py2 (2.6+) and py3.

References #27193
