As part of Metrics Stability KEP we migrated from Prometheus client to Kubernetes Metrics Framework. So we no longer need to depend on promethues client directly.

I configured Bazel to forbid importing prometheus directly. https://github.com/kubernetes/kubernetes/blob/master/hack/verify-prometheus-imports.sh (EDITED)

Example PR that removes reference #85289

There are still couple of directories that need to be cleaned up:

• cluster/images/etcd-version-monitor (@zhouya0, Remove prometheus references from etcd version monitor #89413)
• pkg/master (@zhouya0)
• pkg/scheduler/ (@gavinfish, Cleanup: remove prometheus dependencies for scheduler #98338)
• pkg/volume (@gavinfish, Cleanup: remove prometheus dependencies for volume #98729)
• staging/src/k8s.io/apiserver/pkg/admission/metrics (@tanjunchen, remove prometheus dependencies from k/k #89285)
• staging/src/k8s.io/apiserver/pkg/util/flowcontrol/metrics (@tanjunchen)
• test/e2e_node (@gavinfish)
