343db5b578 Remove references to CoreOS Container Linux 
* CoreOS Container Linux was deprecated in v1.18.3 (May 2020)
in favor of Fedora CoreOS and Flatcar Linux. CoreOS Container
Linux references were kept to give folks more time to migrate,
but AMIs have now been deleted. Time is up.

979c092ef6 Reduce apiserver metrics cardinality of non-core APIs 
* Reduce `apiserver_request_duration_seconds_count` cardinality
by dropping series for non-core Kubernetes APIs. This is done
to match `apiserver_request_duration_seconds_count` relabeling
* These two relabels must be performed the same way to avoid
affecting new SLO calculations (upcoming)
* See https://github.com/kubernetes-monitoring/kubernetes-mixin/issues/498

eb093af9ed Drop Kubelet labelmap relabel for node_name 
* Originally, Kubelet and CAdvisor metrics used a labelmap
relabel to add Kubernetes SD node labels onto timeseries
* With https://github.com/poseidon/typhoon/pull/596 that
relabel was dropped since node labels aren't usually that
valuable. `__meta_kubernetes_node_name` was retained but
the field name is empty
* Favor just using Prometheus server-side `instance` in
queries that require some node identifier for aggregation
or debugging

29b16c3fc0 Change seccomp annotations to seccompProfile 
* seccomp graduated to GA in Kubernetes v1.19. Support for
seccomp alpha annotations will be removed in v1.22
* Replace seccomp annotations with the GA seccompProfile
field in the PodTemplate securityContext
* Switch profile from `docker/default` to `runtime/default`
(no effective change, since docker is the runtime)
* Verify with docker inspect SecurityOpt. Without the profile,
you'd see `seccomp=unconfined`

Fix SELinux race condition on non-bootstrap controllers in multi-controller (#808) 
* Fix race condition for bootstrap-secrets SELinux context on non-bootstrap controllers in multi-controller FCOS clusters
* On first boot from disk on non-bootstrap controllers, adding bootstrap-secrets races with kubelet.service starting, which can cause the secrets assets to have the wrong label until kubelet.service restarts (service, reboot, auto-update)
* This can manifest as `kube-apiserver`, `kube-controller-manager`, and `kube-scheduler` pods crashlooping on spare controllers on first cluster creation

ccee5d3d89 Update from coreos/flannel-cni to poseidon/flannel-cni 
* Update CNI plugins from v0.6.0 to v0.8.6 to fix several CVEs
* Update the base image to alpine:3.12
* Use `flannel-cni` as an init container and remove sleep
* https://github.com/poseidon/terraform-render-bootstrap/pull/205
* https://github.com/poseidon/flannel-cni
* https://quay.io/repository/poseidon/flannel-cni

Background

* Switch from github.com/coreos/flannel-cni v0.3.0 which was last
published by me in 2017 and is no longer accessible to me to maintain
or patch
* Port to the poseidon/flannel-cni rewrite, which releases v0.4.0
to continue the prior release numbering

78e6409bd0 Fix flannel support on Fedora CoreOS 
* Fedora CoreOS now ships systemd-udev's `default.link` while
Flannel relies on being able to pick its own MAC address for
the `flannel.1` link for tunneled traffic to reach cni0 on
the destination side, without being dropped
* This change first appeared in FCOS testing-devel 32.20200624.20.1
and is the behavior going forward in FCOS since it was added
to align FCOS network naming / configs with the rest of Fedora
and address issues related to the default being missing
* Flatcar Linux (and Container Linux) has a specific flannel.link
configuration builtin, so it was not affected
* https://github.com/coreos/fedora-coreos-tracker/issues/574#issuecomment-665487296

Note: Typhoon's recommended and default CNI provider is Calico,
unless `networking` is set to flannel directly.
