[pkg-go] Bug#911434: prometheus: FTBFS with golang-google-grpc/1.11.0-1

[Shengjing Zhu]

Package: prometheus
Version: 2.4.3+ds-1
Severity: serious
Tags: ftbfs
Forwarded: https://github.com/prometheus/prometheus/issues/4587

Dear Maintainer,

I plan to upgrade golang-google-grpc to 1.11.0.

When rebuild the reverse Build-Depends, I notice prometheus FTBFS,

--- FAIL: TestStartupInterrupt (10.51s)
	main_test.go:97: prometheus didn't shutdown gracefully after sending the Interrupt signal

I'm not sure how this test is related to golang-google-grpc.
And upstream has a similar issue, "Flaky shutdown test"
