[WIP] experimenting with encrypted travis tokens

[tansaku]

fixes #70

[tansaku]

I wonder if we need to inject the token directly into the URL like so:

https://#{ENV.fetch("CI_USER_TOKEN")}@github.com/saasbook/hw-ruby-intro-ci.git

that would be a specific change for the CI which I think we should avoid ... what would be nice is some simpler way of checking whether this .netrc thing is doing what we think it should be doing ...

[bill-auger]

i think with https:// git will always require a password for priveledged actions - i wouild assume you would need to write a private key to /home/travis/.ssh/ as a pre-build step and pull with ssh using the form git@github.com:saasbook/hw-ruby-intro-ci

[tansaku]

maybe so @bill-auger but that's not what https://docs.travis-ci.com/user/private-dependencies/#API-Token implies ...

We seem to have access to private repos now, but for some reason we get a single failure that seems unrelated to network access:

cucumber features/autograder_xqueue_stubbed.feature:47

passes locally for me - but on CI gets the following ...
