Remove support for EOL Python 3.3

jdufresne · encukou · commit 6e75fc4b0f1d · 2018-01-10T11:47:25.000+01:00
Python 3.3 is end of life. It is no longer receiving bug fixes including for security issues. It has been EOL since 2017-09-29. For a library focused on authentication, supporting environments that are not receiving security updates sends the wrong message. For additional details, see: https://devguide.python.org/#status-of-python-branches Reduces testing and maintenance resources. python-ldap#154
