Move to client-go 8. (#362)

Not much changes, except for one function that has been deprecated.
However, unless we find a way to use semantic version comparisons like
'^' on a branch name, we would have to update the apimachinery,
apiextensions-apiserver and code-generator dependencies manually.

Also, slash a linter warning about RoleOriginUnknown being not used.
