The default volume type for root & etcd has been updated from `gp2` to `gp3` as of v1.20.0
Updating the doc to reflect this change and add io2 as well as well as note which types can be configured with iops and throughput options.

I opted to just use a *string for the TGW ID in the route task rather than a full TGW task because kops will never be creating TGWs itself, they will always be defined by ID.
Currently, kOps uses cgroupfs cgroup driver for the kubelet and CRIs. This PR defaults
the cgroup driver to systemd for clusters created with k8s versions >= 1.20.
Using systemd as the cgroup-driver is the recommended way as per
https://kubernetes.io/docs/setup/production-environment/container-runtimes/
- Resources
We enable users to set their desired capacity for cluster-autoscaler addon.
There are edge cases, especially in big clusters, where autoscaler needs
to reconcile a large number of objects thus may need increased memory or
increased cpu to avoid saturation.
- Metrics
Cluster autoscaler provides valuable insights for monitoring capacity
allocation and scheduling aspects of a cluster. In this commit, we
add proper annotation on deployment to enable Prometheus scrape metrics.
We also bump patch version of container images.

* perform vendoring related tasks and apply fixes identified from hack/
dissallow spotinst + nlb
remove reflection in status_discovery.go
Add precreated additional security groups to the Master nodes in case of NLB
Remove support for attaching individual instances to NLB; only rely on ASG attachments
Don't specify Classic loadbalancer in GCE integration test
* add utility function to the kops model context to make LoadBalancer comparisons simpler
* use DNSTarget interface when locating DNSName of API ELB
* wip: create target group task
* Consolidate TargetGroup tasks
* Use context helper for determining api load balancer type to avoid nil pointers
* Update NLB creation to use target group ARN from separate task rather than creating a TG in-line
* Address staticcheck and bazel failures
* Removing NLB Attachment tasks because they're not used since we switched to defining them as a part of the ASGs
* Address PR review feedback
* Only set LB Class field for AWS clusters, fix nil pointer

* Addressing PR feedback Renaming task 1. awstasks.LoadBalancer -> awstasks.ClassicLoadBalancer
* Addressing PR feedback Renaming task: ELBName() -> CLBName() / LinkToELB() -> LinkToCLB()
* Addressing PR feedback: Various text changes
* fix export of kubecfg
* address TargetGroup should have the same name as the NLB
* should address error when fetching tags due to missing ARN
* Update expected and crds
* Add feature table to NLB docs

In this commit, we initialize the support of --request-timeout flag on
the configuration of KubeAPIServer so as to enable users for setting
timeout duration value for all kinds of handlers.
