travis-ci failures: keyring in py2.7?

[keflavich]

We have several parallel ci errors that appear to be the same thing:

https://travis-ci.org/astropy/astroquery/jobs/363777242
https://travis-ci.org/astropy/astroquery/jobs/363867194
https://travis-ci.org/astropy/astroquery/jobs/364053671

They're failing on this stage:

        - os: linux
          stage: Test docs, astropy dev, and without optional dependencies
          env: PYTHON_VERSION=2.7
               CONDA_DEPENDENCIES='requests beautifulsoup4 html5lib keyring'

and seem to be keyring import failures.

Perhaps unrelated but when inspecting the first log, I saw these:

astroquery/sdss/setup_package.py:2: RuntimeWarning: Parent module 'astroquery.sdss' not found while handling absolute import
  import os
astroquery/mast/tests/setup_package.py:1: RuntimeWarning: Parent module 'astroquery.mast.tests' not found while handling absolute import
  import os

As for keyring, I wonder if opening an issue at https://github.com/jaraco/keyring/issues would help.

it might be a conda failure though?

I have seen some packages failed mysteriously, only to pass later when you rerun the job without any code changes. But there was also one that is still failing (Appveyor + PY2). So... 🤷‍♀️
