Minimum supported versions are now Django 2.0, Python 3.5. This touches a lot of code, to: * Remove obsolete portability code and workarounds (six, backports of email parsers, test utils, etc.) * Use Python 3 syntax (class defs, raise ... from, etc.) * Correct inheritance for mixin classes * Fix outdated docs content and links * Suppress Python 3 "unclosed SSLSocket" ResourceWarnings that are beyond our control (in integration tests due to boto3, python-sparkpost)
