Dalton Hubble da5d2c5321 Remove GCP firewall rule allowing Nginx Ingress health
* Nginx Ingress addon no longer uses hostNework so Prometheus may
scrape port 10254 via the CNI network, rather than via the host
address

Dalton Hubble bceec9fdf5 Sort firewall / security rules and add comments
* No functional changes to network firewalls

Dalton Hubble 0c4d59db87 Use global HTTP/TCP proxy load balancing for Ingress on GCP
* Switch Ingress from regional network load balancers to global
HTTP/TCP Proxy load balancing
* Reduce cost by ~$19/month per cluster. Google bills the first 5
global and regional forwarding rules separately. Typhoon clusters now
use 3 global and 0 regional forwarding rules.
* Worker pools no longer include an extraneous load balancer. Remove
worker module's `ingress_static_ip` output.
* Add `ingress_static_ipv4` output variable
* Add `worker_instance_group` output to allow custom global load
balancing
* Deprecate `controllers_ipv4_public` module output
* Deprecate `ingress_static_ip` module output. Use `ingress_static_ipv4`

to health and metrics

Dalton Hubble c2b719dc75 Configure Prometheus to scrape Kubelets directly
* Use Kubelet bearer token authn/authz to scrape metrics
* Drop RBAC permission from nodes/proxy to nodes/metrics
* Stop proxying kubelet scrapes through the apiserver, since
this required higher privilege (nodes/proxy) and can add
load to the apiserver on large clusters

Dalton Hubble 2b74aba564 Add Google Cloud fedora-atomic module
* Network load balancer for ingress doesn't work yet
because Compute Engine packages are missing
* port-forward / socat is broken
