There are still some dependencies that we need to make work to fully
deactivate the legacyImports in the future. I'll start opening PRs
against those other repositories.

This daemonset doesn't affect workload availability so allow its rollout to
be parallelized.

Merged https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/463 to remove duplicate entries for memory usage, however I'd like to move these changes to the Prometheus-Operator helm chart(https://github.com/helm/charts/pull/23024#issuecomment-661967101). I've regenerated the dashboards/alerts.

kube-apiserver has a histogram etcd_request_duration_seconds that
measures latency between the kube-apiserver and etcd instance.
This metrics is currently dropped by cluster-prometheus. Enable
this metrics so we have visibility into etcd latency.

We ensured that this does not enable other unwanted metrcis

count by(name) ({name=~"etcd_request.+"})

etcd_request_duration_seconds_bucket
etcd_request_duration_seconds_count
etcd_request_duration_seconds_sum

This reverts commit cdaaf3d5.
