Drop Python 2.6 support?

[thedrow]

Python 2.6 is very old.
If people need it, they can use previous versions.

What do you think?

I have no particular love for keeping 2.6 (it's been end-of-life for nearly 5 years), but on the other hand I haven't yet run into anything that's a major pain to make work on Python 2.6 so I've just kept it. @jamesls, do you have an opinion?

Drop it and Python 3.3.

They're both EOL and longer receiving security updates (or any updates) from the core Python team.

They're also little used. Here's the pip installs for fakeredis from PyPI for July 2018:

python_version	percent	download_count
2.7	43.69%	15,102
3.6	30.85%	10,661
3.5	14.93%	5,160
3.4	9.40%	3,249
3.7	1.06%	368
2.6	0.05%	17
3.3	0.02%	6
Total		34,563
