Upstream changes:
* Release notes for 3.0.20201209
* Handling hanging list command from etcd client during reconciliation loop
* Update dependencies to match kOps 1.19
* Include IPs in peer certificates
* Use etcd v3.4.13 in tests
* Eager-broadcast leadership on every leader iteration
* Update Go to 1.15.7
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.

Introduce a new "encapsulationMode" field in Calico's portion of the
Cluster specification to allow switching between the the IP-in-IP and
VXLAN encapsulation protocols. For now, we accept the values "ipip"
and "vxlan," and forgo a possible "none" value that would disable
encapsulation altogether (at least for the default Calico IP pool).
Augment the default-populating procedure for Calico to take this field
into account when deciding both which networking backend to use and
whether to use IP-in-IP or VXLAN encapsulation for the default IP
pool. Note that these values supplied for the "CALICO_IPV4POOL_IPIP"
and "CALICO_IPV4POOL_VXLAN" environment variables in the "calico-node"
DaemonSet pod spec only matter for creating the "default" IPPool pool
object when no such objects already exist.
Generalize the documentation for the "crossSubnet" field to cover
environments more broad than just AWS, as Calico can employ this
selective encapsulation in any environment in which it can detect
boundaries between subnets.
