require non-RSA SSH keys or a workaround snippet

Dalton Hubble fa3184fb9c Relax terraform-provider-ct version constraint 
* Allow terraform-provider-ct versions v0.6+ (e.g. v0.7.1)
Before, only v0.6.x point updates were allowed
* Update terraform-provider-ct to v0.7.1 in docs
* READ the docs before updating terraform-provider-ct,
as changing worker user-data is handled differently
by different cloud platforms

Dalton Hubble e826b49648 Update Matchbox profile to use initramfs and rootfs images 
* Fedora CoreOS stable (after Oct 6) ships separate initramfs
and rootfs images, used as initrd's
* Update profiles to match the Matchbox examples, which have
already switched to the new profile and to remove the unused
kernel args
* Requires Fedora CoreOS version which ships rootfs images
(e.g. stable 32.20200923.3.0 or later)

items https://github.com/poseidon/typhoon/issues/703

Flatcar Linux's images be manually uploaded (like GCP and
DigitalOcean)

Dalton Hubble 70bdc9ec94 Allow bootstrap re-apply for Fedora CoreOS GCP 
* Problem: Fedora CoreOS images are manually uploaded to GCP. When a
cluster is created with a stale image, Zincati immediately checks
for the latest stable image, fetches, and reboots. In practice,
this can unfortunately occur exactly during the initial cluster
bootstrap phase.

* Recommended: Upload the latest Fedora CoreOS image regularly
* Mitigation: Allow a failed bootstrap.service run (which won't touch
the done ConditionalPathExists) to be re-run by running `terraforma apply`
again. Add a known issue to CHANGES
* Update docs to show the current Fedora CoreOS stable version to
reduce likelihood users see this issue

 Longer term ideas:

* Ideal: Fedora CoreOS publishes a stable channel. Instances will always
boot with the latest image in a channel. The problem disappears since
it works the same way AWS does
* Timer: Consider some timer-based approach to have zincati delay any
system reboots for the first ~30 min of a machine's life. Possibly just
configured on the controller node https://github.com/coreos/zincati/pull/251
* External coordination: For Container Linux, locksmith filled a similar
role and was disabled to allow CLUO to coordinate reboots. By running
atop Kubernetes, it was not possible for the reboot to occur before
cluster bootstrap
* Rely on https://github.com/coreos/zincati/issues/115 to delay the
reboot since bootstrap involves an SSH session
* Use path-based activation of zincati on controllers and set that
path at the end of the bootstrap process

* Remove docs for the `asset_dir` variable and deprecate

* Typhoon v1.17.0 introduced a new mechanism for managing
and distributing generated assets that stopped relying on
writing out to disk. `asset_dir` became optional and
defaulted to being unset / off (recommended)

Dalton Hubble ab7913a061 Accept initial worker node labels and taints map on bare-metal 
* Add `worker_node_labels` map from node name to a list of initial
node label strings
* Add `worker_node_taints` map from node name to a list of initial
node taint strings
* Unlike cloud platforms, bare-metal node labels and taints
are defined via a map from node name to list of labels/taints.
Bare-metal clusters may have heterogeneous hardware so per node
labels and taints are accepted
* Only worker node names are allowed. Workloads are not scheduled
on controller nodes so altering their labels/taints isn't suitable

```
module "mercury" {
  ...

  worker_node_labels = {
    "node2" = ["role=special"]
  }

  worker_node_taints = {
    "node2" = ["role=special:NoSchedule"]
  }
}
