bump google auth version

[max-sixty]

Closes #73

[parthea]

Could we upgrade to the latest version of google-auth to take advantage of the latest fixes? The latest version 1.4.1 might also fix #136 . I see a note in the google-auth release notes that says 'default() now checks for the project ID environment var before warning about missing project ID.'

[max-sixty]

Yes, to be clear, we want to make that a min version?

I couldn't find a .stickler.yml file in this repository. I can make one for you, or you can create one by following the documentation.

@parthea gentle ping

[tswast]

Hmm, I'm not so sure about bumping up a dependency version here just for upstream bug fixes. This is technically a breaking change and I know it would cause some hurt inside Google, which is ironically slow to make version upgrades of these packages.

We should keep our CI and this in sync, though. What was the reason for bumping the version to 1.0.2 in #139 ?

@tswast @maxim-lian
How do you feel about removing pinning altogether ?

[tswast]

I'd be more okay with that.

[max-sixty]

OK - let's do that

I think we can then refer those issues (#73 and #136) upstream - they're not pandas-gbq specific. Is that right?

[max-sixty]

Updated!

Thanks @maxim-lian !
