* Emphasize that Container Linux Configs have been dropped and
that Butane is the way forward to use modern Ignition v2
* Include some links to Flatcar Linux docs
* Update Makefile and docs for v0.10.0 release process
* Deprecate rendering Container Linux Configs
* Use tools like [poseidon/ct](https://github.com/poseidon/terraform-provider-ct) or
[butane](https://coreos.github.io/butane/getting-started/) to validate and convert a
Butane Config (`focs` or `flatcar`) to Ignition (for Matchbox to serve)
* Please migrate to serving CoreOS Ignition directly, the Container
Linux related HTTP and gRPC endpoints will be removed in future
* 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 Terraform examples to use Terraform v0.13
* Refresh examples to show Fedora CoreOS and Flatcar Linux
* Remove the etcd3 example, not worth it to maintain
* Matchbox is published as a binary or container image,
not planning to resume RPM/Copr publishing since its a
pain
* Publishing to Copr repo stopped in v0.6 (3 years ago)
