* Discontinue using Matchbox's Container Linux Config features
* Flatcar Linux OS now supports Ignition v2.13+ which means it
can accept Ignition v3.x spec's, like Fedora CoreOS. Matchbox
supports this by serving Ignition documents directly
* Users of the poseidon/matchbox Terraform provider can pass
a `matchbox_profile` `raw_ignition` contents with the desired
Ignition v3.3 spec
* Users of the poseidon/ct Terraform provider can write Butane
Config YAML, perform templating, and render an Ignition document
using either the fcos or the flatcar variant
* Add initrd=main karg directive for UEFI (ignored by BIOS)
* Update Butane config version to v1.4.0 (generates Ignition v3.3.0)
in `fedora-coreos` and `fedora-coreos-install` examples
* Update virt-install flag --os-variant
* Removed virt-install deprecated flag --os-type
* Remove virt-install QEMU/KVM event preserve since it apparently
wasn't implemented anyway and QEMU/KVM now warns about it
* Remove serial consol kernel argument from examples, but still
mention it in docs

When coreos-installer is running from the live image, it no longer needs
a separate install image, since by default it installs from content
embedded in the live system.
* Update Fedora CoreOS live PXE and disk install examples to
Fedora 33
* Increase libvirt VM memory from 2GB to 3GB to support live
PXE example, which is mostly just for laptop examples/demos.
Reduce the VM count from 3 to 2 to compensate.
* Change `fedora-coreos.ign` to suggest using an ed25519 SSH
key since Fedora CoreOS 33 disables RSA SHA1 (256 is still ok
but most people won't know which they have)
* Refactor examples to boot provision minimal hosts
with Fedora CoreOS or Flatcar Linux
* Remove the etcd3 cluster example or other specific
kinds of hosts
* Update script get-fedora-coreos
* Remove script get-coreos
* Use our own infra to perform image builds and push images.
Provides future options for publishing images to multiple
image registries and for multiple architectures, while keeping
push permissions in-house
* Remove Travis ability to push to Quay
* Use Travis only for Go tests of Pull Requests
* Use `quay.io/dghubble/protoc` as the standard codegen
environment across projects. Pin a version (v3.10.1)
* Generated code is now automatically ignored by golint
based on the comment header, which will simplify linting
* Upgrade protobuf from 2bba0603135d to v1.3.2
* Upgrade grpc from v1.2.1 to v1.25.1
* Remove `get-protoc` and `codegen` scripts
* rkt achieved its mission creating the OCI standard,
pluggable runtimes, and prevented Docker world
domination. We can now proceed with disarmament
* Few, if any, developers still use rkt locally
* Local QEMU/KVM tutorials use either docker or rkt/acbuild,
but they're dated. rkt and acbuild are no longer in mainstream
use since they successfully drove OCI standardization
* Remove the rkt examples, as they are just more difficult for
newcomers to use and seldom maintained at this point
* Retain Docker examples, although podman will likely supplant
all docker usage in future
* Add ipxe.efi to dnsmasq image's /var/lib/tftpboot directory
* Add initrd kernel argument respected only by UEFI
https://github.com/coreos/bugs/issues/1239
* Improve network-setup docs and scripts to cover UEFI clients
and to support launching UEFI QEMU/KVM clusters locally
* Reduce references to grub.efi flow, its not a happy path
