Note for the metrics configuration for etcd 
As etcd is running directly as a service on the master nodes it is easy to overlook that different ports are needed to expose metrics for multiple etcd clusters on the master nodes. It can be easy to forget this if you otherwise just deal with containers and pods... 😅  A reminder and clarification doesn't hurt.

Add support for defining a transit gateway for a default route 
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.

Bharath Vedartham a8d709acf2 Default cgroup driver to systemd from k8s 1.20 
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

[addons/CA] Add support for specifying resources and metrics 
- 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.
