user-sync should work in Python 3 as well as Python 2

As Python 2 end-of-life is approaching, we need to port user-sync to Python 3 for customers who are transitioning. As with umapi-client, we should support both Python 2 and 3.

@ianmak I'd like you to take a shot at this. First look at the sources for the umapi-client, where I did this conversion a while ago. The key is to use the six module, which is a shim layer that maps both the 2.7 and 3.x modules to the same namespace. Then you find all the places where 2.7-isms are used, and you convert them to be the six-compatible version which also run in 3.x. Do some research and then tell me what you think; I think this could be right up your alley.

sure thing I will take a shot at this.
