Use assertEqual instead of assertEquals in unitttest

[ZhiQiang Fan]

I noticed that [keystone, python-keystoneclient, python-neutronclient] configure tox.ini with py33 test, however, assertEquals is deprecated in py3 but ok with py2, so i think it is better to change all of assertEquals to assertEqual

Can we support this via hacking before producing fixes? I'd rather just fix this kind of thing once.

I reviewed the code for the unittests and I didn't see any "assertEquals" in the projects ​
  python-keystoneclient and keystone.

I think this bug should be closed for these modules.

    pep8 fix: assertEquals -> assertEqual

    Change is necessary due to update to hacking 0.8.0, which is in
    alignment with project standards.
