Dalton Hubble 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

Dalton Hubble 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

Dalton Hubble 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

* Update CNI plugins from v0.6.0 to v0.8.6 to fix several CVEs
* Update the base image to alpine:3.12

* 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

* Before, the requirement was v0.3.0 <= version < v0.4.0

Dalton Hubble 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.
