Use global HTTP/TCP proxy load balancing for Ingress on GCP

Browse Source 
* 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`

* Switch `kube-apiserver` port from 443 to 6443 ([#248](https://github.com/poseidon/typhoon/pull/248))
* Combine apiserver and ingress NLBs ([#249](https://github.com/poseidon/typhoon/pull/249))
* Simplify clusters to come with one NLB. Reduce cost by ~$18/month per cluster.
* Reduce cost by ~$18/month per cluster. Typhoon AWS clusters now use one network load balancer
* Users may keep using CNAME records to `ingress_dns_name` and the `nginx-ingress` addon for Ingress (up to a few million RPS)
* Users with heavy traffic (many million RPS) should create a separate NLB(s) for Ingress instead
* Listen for apiserver traffic on port 6443 and forward to controllers (with healthy apiserver)
* Listen for ingress traffic on ports 80/443 and forward to workers (with healthy ingress controller)
* Worker pools (advanced) no longer include an extraneous load balancer
* Worker pools no longer include an extraneous load balancer
* Disable detailed (paid) monitoring on worker nodes ([#251](https://github.com/poseidon/typhoon/pull/251))
* Favor Prometheus for cloud-agnostic metrics, aggregation, alerting, and visualization
