hi, @dgrisonnet @serathius could we merge this PR？
Otherwise, release-0.5's ci will not run properly. Unless we no longer maintain this branch.

[dgrisonnet]

Release-0.5 is running on unsupported versions of both Go and Kubernetes, so it is very unlikely that we will push any fixes to it

[yangjunmyfm192085]

ok, I got it.
