I think an additional question is if TravisCI is still in use since this file was last updated 4 years ago a references legacy versions of of Go and it's runner.

@tenthirtyam I think that if we eliminate gogetcookie.sh, .travis.yml should go as well. If we keep the yml file, we should keep gogetcookie.sh as well.

I've seen this copied to some other provider repos, not just our own.

This script sets up a Git cookie for authenticating with a googlesource.com repository.
The cookie contains credentials (git-paul.hashicorp.com=1/...) that are likely used for accessing private repositories or performing authenticated Git operations on the googlesource.com domain, which should not be needed by this project.
