Fix TestAccDataprocCluster_AttachedDiskConfigWorker

[SirGitsalot]

The main point of this PR is to fix the "Error 400: Permissions are missing for the default service account" error by putting the cluster into the same region as the buckets. Stockouts are still a big problem for the dataproc tests, but switching to c4-standard-2 might help with that.

Fixes hashicorp/terraform-provider-google#28701 (at least it fixes it locally, we'll see what happens on CI) Does not fix the issue mentioned in the comment regarding oneof ... must be specified which I think is a different problem.

Just want to double-check that this has to do with regions? I didn't know that IAM permissions could differ between regions... also, if it's based on the configuration to that extent, why is this passing in beta?

[melinath]

(I was wondering if this might be missing IAM bootstrapping: https://googlecloudplatform.github.io/magic-modules/test/test/#iam-resources)

[SirGitsalot]

The region ends up in the name of the buckets, which are dataproc-[staging|temp]-[region]-[project number]-[seemingly random suffix]. The beta project has buckets for both us-central1 and asia-east1 while the ga project only has us-central1. The compute service accounts in both projects have the exact same set of roles, which makes me think its' the absence of the bucket rather than the absence of a role that's causing the failure.

The buckets should be created automatically, since this test doesn't specify custom buckets. If it's failing to do so in the GA project it doesn't appear to be due to IAM roles on the compute SA (or on the test runner SA, which between GA and beta does have a different set of roles, but both have "Owner" and "Storage Admin")
