Dependency pyrsistent dropped py2 support in 0.17.0

Hi there! I'm not sure if jsonschema plans to keep python2 support, but just realized the dependency pyrsistent dropped python 2 support in its 0.17.0 release today.

Hi!

The next version of jsonschema will be py3-only (though will declare so appropriately via python_requires, so nothing in Py2 will break).

The same should be true of pyrsistent I hope (that it properly declares python_version, so Py2 will still work even if you haven't pinned your dependencies). If that's not the case though definitely worth bringing up there.

jsonschema-3.2.0 doesn't work in python2 anymore, can we have jsonschema-3.2.x with pyrsistent version restricted to <0.17.0 ?

Sounds like the pyrsistent release indeed doesn't/didn't include python_requires. It's being addressed here though: tobgu/pyrsistent#208.

That's where the fix would go so likely worth following that issue.
