storage: RetryClientTest.HedgedReadRecordsMetricsOnGlobalMeterProvider leaking mock objects

Beginne in google/cloud/storage/internal/connection_impl_test.cc bei der in den Zeilen 829, 830, 835 und 857 gemeldeten Mock-Einrichtung und konzentriere dich auf RetryClientTest.HedgedReadRecordsMetricsOnGlobalMeterProvider. Führe //google/cloud/storage:internal_connection_impl_test mit randomisierten Tests aus und bestätige, dass es ohne die Meldung durchgesickerter Mock-Objekte erfolgreich ist.

Step #2 - "build.sh": ERROR: 4 leaked mock objects found at program exit. Expectations on a mock object are verified when the object is destructed. Leaking a mock means that its expectations aren't verified, which is usually a test bug. If you really intend to leak a mock, you can suppress this error using testing::Mock::AllowLeak(mock_object), or you may use a fake or stub instead of a mock.
