python3 support

Should add python3 support in future.

Before adding py3 support, should move zuul job setting from project config to networking-zvm. Some reference info for this:

The current tox.ini for ceilometer-zvm includes this line [1] similar to what ceilometer-powervm was doing up until recently:

   -egit+https://github.com/openstack/ceilometer@master#egg=ceilometer

We found that this no longer works since ceilometer was added to upper-constraints [2]. We first got things working again by [3] and are now improving on that by [4]. I expect you will need to make similar changes.

I was going to propose this to ceilometer-zvm for you, but then noticed that you don't even have a zuul.yaml file. You're missing changes like [5] adding lower-constraints checking and [6] for the python3-first effort. So that is probably a bigger issue to address first (and for networking-powervm and nova-zvm-virt-driver as well as ceilometer-zvm). When you get to the python3 stuff, I suggest you work with dhellmann on that. He's got scripts to generate at least some of those commits.
