Drop support for EOL Pythons

Python 2.6, 3.2, and 3.3 are end of life. They are no longer receiving
bug fixes, including for security issues. Python 2.6 went EOL on
2013-10-29, Python 3.2 on 2016-02-20, and Python 3.3 on 2017-09-29. For
additional details on support Python versions, see:

Removing support for EOL Pythons will reduce testing and maintenance
resources.

Using pypinfo, here are the PyPI download statistics for the last 30
days, showing low numbers for EOL Pythons.

| python_version | percent | download_count |
| -------------- | ------: | -------------: |
| 2.7            |  61.50% |        785,047 |
