This is a rename of the osctl binary. We decided that talosctl is a
better name for the Talos CLI. This does not break any APIs, but does
make older documentation only accurate for previous versions of Talos.

This PR introduces a new strategy for upgrades. Instead of attempting to
zap the partition table, create a new one, and then format the
partitions, this change will only update the `vmlinuz`, and
`initramfs.xz` being used to boot. It introduces an A/B style upgrade
process, which will allow for easy rollbacks. One deviation from our
original intention with upgrades is that this change does not completely
reset a node. It falls just short of that and does not reset the
partition table. This forces us to keep the current partition scheme in
mind as we make changes in the future, because an upgrade assumes a
specific partition scheme. We can improve upgrades further in the
future, but this will at least make them more dependable. Finally, one
more feature in this PR is the ability to keep state. This enables
single node clusters to upgrade since we keep the etcd data around.

This PR will allow users to set the `persist: true` value in their
config data to tell talos not to re-pull the config data at each reboot.
The default will still remain as a "pull every time" methodolgy in order
to encourage immutability by default.

This makes use of the external procfs pacakge that is based on the
pacakge we are removing here.

This allows users to specify well known query parameters in `talos.config`.
The only supported parameter in this change is `uuid`. This will send
the node's UUID determined from SMBIOS along with the request for the
config.

machined's main.go waits for boot sequence to finish, while metal
platform initializer tries to send a message to the event bus without
any listeners, so this is pure deadlock.
Resolve that by panicking from initializer, this aborts phase and
sequence, and leads to reboot on panic. Not really clean as it leaves
scary stacktraces in the dmesg, but it works. Cleanup might be done by
introducing error value for reboot, and ignoring it when printing the
errors.

This PR will move to using a `ConfiguratorBundle` interface for our
various config data files. This will allow us to easily abstract away
various versions and easily get the data with functions.

This enusres that we default to using `guestinfo` for VMware's config
source, and that we use tty0 instead of ttyS0 for the console.

This introduces the notion of metadata for a node. In this initial pass
there are only two fields. A timestamp to indicate when the install was
performed, and a field to indicate if the install was performed as part
of an upgrade.

This should provide a better UX around misconfigured Talos nodes. It is
just the start of something we can expand on.

Instead of passing around a struct, it is better if we pass around an
interface that describes the behavior we want. The Runtime interface
provides a common place to describe runtime specific parameters. This
initial implementation offers the runtime mode, the platform specifics,
and the config.

This brings in a few minor improvements to the metal platform. The first
is to use talos.config=metal-iso to indicate that the machine's config
can be found in an ISO image. The second is a fix to ensure that /mnt
exists.
This adds support for creating more than one node using the qemu-boot.sh
script.

This moves from translating a config into an internal config
representation, to using an interface. The idea is that an interface
gives us stronger compile time checks, and will prevent us from having to copy
from on struct to another. As long as a concrete type implements the
Configurator interface, it can be used to provide instructions to Talos.

This change ensures that the installer has access to the machine config
so that it can set the extra kernel arguments when installing.
