[Speed] Update Django from 1.11 to 2.0? What about Python 2.7 and PyPy2?

Hi,

I regularly update requirements of the performance benchmark suite. Django 2.0 is now proposed, but it's incompatible with Python 2.7 and PyPy2.

• Is it ok to skip the django_template benchmark on Python 2.7 and PyPy2?
• Should we add a different benchmark?
• Or test different Django version depending on the Python version?

I'm fine with testing Django 1.11 on Python 2.7 and test Django >= 2.0 on Python 3, but maybe others have different opinion on that?

The main question is the expected behaviour when comparing Python2 and Python3 with performance on the Django template benchmark.
