Dalton Hubble 43e05b9131 Enable kube-proxy metrics and allow Prometheus scrapes
* Configure kube-proxy --metrics-bind-address=0.0.0.0 (default
127.0.0.1) to serve metrics on 0.0.0.0:10249
* Add firewall rules to allow Prometheus (resides on a worker) to
scrape kube-proxy service endpoints on controllers or workers
* Add a clusterIP: None service for kube-proxy endpoint discovery

Dalton Hubble 178afe4a9b Reduce apiserver metrics cardinality and extraneous labels
* Stop mapping node labels to targets discovered via Kubernetes
nodes (e.g. etcd, kubelet, cadvisor). It is rarely useful to
store node labels (e.g. kubernetes.io/os=linux) on these metrics
* kube-apiserver's apiserver_request_duration_seconds_bucket metric
has a high cardinality that includes labels for the API group, verb,
scope, resource, and component for each object type, including for
each CRD. This one metric has ~10k time series in a typical cluster
(btw 10-40% of total)
* Removing the apiserver request duration outright would make latency
alerts a NoOp and break a Grafana apiserver panel. Instead, drop series
that have a "group" label. Effectively, only request durations for
core Kubernetes APIs will be kept (e.g. cardinality won't grow with
each CRD added). This reduces the metric to ~2k unique series

Dalton Hubble 525ae23305 Add node-exporter alerts and Grafana dashboard
* Add Prometheus alerts from node-exporter
* Add Grafana dashboard nodes.json, from node-exporter
* Not adding recording rules, since those are only used
by some node-exporter USE dashboards not being included

Dalton Hubble 33d4c2fd68 Add explicit annotation for Prometheus port to scrape
* Without the prometheus.io/port annotation, Prometheus
service discovery can scrape other Prometheus ports that
may be available.
* For example, Prometheus sidecars (not included) may
be scraped and that may be unintended

Dalton Hubble de90cb9246 Remove kube-state-metrics addon-resizer
* addon-resizer is outdated and has been dropped from

Dalton Hubble 19de38b30d Fix Prometheus etcd metrics scraping
* Prometheus was configured to use kubernetes discovery
of etcd targets based on nodes matching the node label
node-role.kubernetes.io/controller=true
* Kubernetes v1.16 stopped permitting node role labels
node-role.kubernetes.io/* so Typhoon renamed these labels
(no longer any association with roles) to
node.kubermetes.io/controller=true
* As a result, Prometheus didn't discover etcd targets,
etcd metrics were missing, etcd alerts were ineffective,
and the etcd Grafana dashboard was empty
* Introduced: https://github.com/poseidon/typhoon/pull/543

* This reverts commit 6e5d66cf66
* kube-state-metrics v1.6.0-rc.0 fires KubeDeploymentReplicasMismatch
alerts where its own Deployment doesn't have replicas available,
(kube_deployment_status_replicas_available) even though all replicas
are available according to kubectl inspection
* This problem was present even with the CSR ClusterRole fix
