Make jwk_data get respect ssl_verify=no

Take the value off of the given AuthClient object.
Closes #160

It turns out this was the only call where verify wasn't set.

I think I might be the only person who cares about this?

I'm curious where you're actually running into an error. All our Auth environments should pass verification, no?

This also seems to have a legitimate test failure.

I'll take a look at the test failure tomorrow.

I see this on Python2, as an SNI issue. I can either turn off verification or fix the actual problem. While working up the fix, I tried turning off verification. I'm still working on getting my SNI change in place, but figured that this would be good to take care of as well.

The AppVeyor build passed because it doesn't run the python-jose dependent tests.

Amended my commit to include a very minor tweak to add the _verify property to the mocked AuthClient used in those tests. The inscrutable failure messages came of that value being a mock.Mock instead of a bool or string.

@jaswilli, can I ask that we push this through?

I can't get this internal issue fixed -- I'm having trouble even figuring out what's wrong -- so this is actually blocking me from assembling some working components.
