Removing Python 2.7 support from Twisted.

rodrigc wrote in #9278:

"I did the following to enable more warnings when running trial using Python 3.5 under Fedora 25:

python -Wall -m twisted.trial twisted

I saw a lot of ResourceWarnings for example:

These can cause spurious test failures on Python 3 and resource leaks on PyPy.  As they're discovered, they should be fixed.

Support PyPy as a platform.

This means getting this buildbot green - ​http://buildbot.twistedmatrix.com/builders/trusty64-pypy-2.4/ - and adding it to the supported list.

Make Twisted completely compatible with a reasonable Python 3.x release.

Tickets for fixing problems introduced by Python 3.x porting work should also be added to this milestone.

Publish PEP 561 stubs so that folks can type-check against Twisted.
