[Vote] Deprecate Python2 Support

[antinucleon]

As we discussed in #2715, most of us agree with switch to Python3 starts with 0.6 release. I want to start a vote to deprecate Python2 support & test in our current master branch.

+1. We (The relay crew) often find not having py3 features(fstring, keword only argument, type annotation, nonlocal) inconvenient. Can we get it to 3.6? fstring(3.6 feature) is used heavily in the relay ahead of time compiler that will be opensourced soon.

+1, I think we agreed on python3.5 support to be safe because many users' system still only have 3.5 installed. For new features, we can depend on 3.6 if it is isolated enough.
