Duplicate metrics from Stackdriver for stackdriver_pubsub_topic_pubsub_googleapis_com_topic metrics

Không có tệp mã nguồn hoặc bài kiểm thử nào được nêu. Hãy bắt đầu bằng việc xem xét đường dẫn thu thập metric của stackdriver_exporter và issue liên quan #103, sau đó xác định cách tái hiện các metric Stackdriver bị trùng; phần hoàn tất phải bao gồm nguyên nhân đã được xác nhận và hướng dẫn được ghi lại hoặc một fix đã được kiểm thử để ngăn lỗi scrape.

For a while our prometheus was not able to scrape any metrics from the stackdriver_export with the following error:
