Adds gen3 token handling

[bwalsh]

The PR contains one new feature:

• An auth helper: anvil.Gen3TerraAuth. This class extends the pattern already in place in the gen3 python library here

The class intercepts calls to the gen3 endpoint and ensures that:

• an access token, retrieved from terra is present on the request
• in the event of an authorization failure, a fresh token is retrieved

We created an issue to track testing progress #22

Made great progress during week of 7/13. Was able to pick up and test this code.

However, somethings seems to have changed. Last week when I linked terra to anvil, under “IDENTITY & EXTERNAL SERVERS”, login to NHGRI AnVIL Data Commons Framework Services I was able to login with my google Id.

When I did that, everything worked as expected. Now, when I re-link terra to anvil, I’m presented with a NIH login. When I use that Id, the tests no longer work

However, checking the swagger api, where I can still authenticate using my google id, the call works.
