Code should use 'is not None' instead of '!= None'

[Johannes Erdfelt]

pep8 complains that some code should use 'is not None' instead of '!= None':

openstack/common/cfg.py:525:28: E711 comparison to None should be 'if cond is not None:'
        if deprecated_name != None:
                           ^
openstack/common/cfg.py:544:33: E711 comparison to None should be 'if cond is not None:'
        if self.deprecated_name != None:
                                ^
openstack/common/cfg.py:758:33: E711 comparison to None should be 'if cond is not None:'
        if self.deprecated_name != None:
                                ^
