monitoring.api.v3.api-client.custom_metric_test: test_custom_metric failed

Note: #7105 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 (7c48837), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

This appears to have failed once on an InternalError. The last instance of a test failure was in November (#7105). A low rate of internal errors is OK. If this becomes more frequent, we can reach out to the API team.
