* Refactor project iam binding and member resources to improve reusability
* Use default mask when updating project iam policy
* Add a doc comment for the ResourceIamUpdater interface
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.
Adds the google_project_iam_member resource, which just ensures that a
single member has a single role.
google_project_iam_member should not be used to grant permissions to a
role controlled by google_project_iam_binding or to a policy controlled
by google_project_iam_policy, as they'll fight for control.
