This reverts commit 8ab9d96d25 and revives
the original commit that adds t.Parallel to all acceptance tests. It
turns out test failures were unrelated to this change (rather, they were
related to quota issues).
This reverts commit 42de44592f. It appears
there might be thread-safety issues as panics have started occuring when
parallism is ramped up. Reverting for now while investigating.
Tests need to have unique names. Whoooops.
Also, the Elem property accepts an interface I guess, which means we
actually need the struct type repetition there.
Add a resource that manages just a single binding within a Google
project's IAM Policy.
Note that this resource should not be used when
google_project_iam_policy is used, or they will fight over which is
correct.
This also required wrapping the error returned from setProjectIamPolicy,
as we need to test to see if it's a 409 error and retry, which can't be
done if we just use fmt.Errorf.
