What happened:

Failing checks in #7728 due to module dependency version mismatch, see Circle-CI logs.

Run Kubernetes tests check fail with following error:

# github.com/coredns/ci/test/kubernetes [github.com/coredns/ci/test/kubernetes.test]
./metrics_test.go:87:15: undefined: expfmt.NewTextParser
FAIL    github.com/coredns/ci/test/kubernetes [build failed]
FAIL

What you expected to happen:

It should pass.

How to reproduce it (as minimally and precisely as possible):

Create a change into a PR in https://github.com/coredns/coredns and see that check failing (This seems to not fail systematically).

Anything else we need to know?:

Either update all dependencies in https://github.com/coredns/ci or revert coredns/ci#165 by using var tp expfmt.TextParser instead of expfmt.NewTextParser.

Also, Consider adding comprehensive testing to https://github.com/coredns/ci
