python34 in testing for EPEL6

[Tim Orling]

I came across a need for python34 in CentOS 6.8 and decided to go ahead and package it for EL6 (SCLs were already available). I have also packaged a number of other python3 modules, which are also in testing. If you are interested, please take a moment to review:

Any testing and karma is much appreciated.
