iam.api-client.service_accounts_test: test_service_accounts failed

Note: #3499 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (6d2ae3a), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

I'm not worrying this flake too much. My hypothesis is that the service somehow failed to fetch the iam configuration and returns an error. Downgrading to P2.

I'll consult the product eng team.
