Filesystem creation step is moved on the later stage: when Talos mounts
the partition for the first time.
Now it checks if the partition doesn't have any filesystem and formats
it right before mounting.
Additionally refactored mount options a bit:
- replaced separate options with a set of binary flags.
- implemented pre-mount and post-unmount hooks.
And fixed typos in couple of places and increased timeout for `apid ready`.

Modify provision library to support multiple IPs, CIDRs, gateways, which
can be IPv4/IPv6. Based on IP types, enable services in the cluster to
run DHCPv4/DHCPv6 in the test environment.
There's outstanding bug left with routes not being properly set up in
the cluster so, IPs are not properly routable, but DHCPv6 works and IPs
are allocated (validates DHCPv6 client).

ECDSA keys are smaller which decreases Talos config size, they are more
efficient in terms of key generation, signing, etc., so it makes boot
performance better (and config generation as well).

This fixes spurious race conditions when user disks are partitioned
and formatted in `mountUserDisks` task. While this task runs, `udevd` is
running to allow various `/dev/` symlinks to be used for user disks.
At the same time `udevd` might trigger syscall `BLKRRPART` at any time
concurrently with Talos which leads to a race on kernel side when Talos
tries to update kernel partition table while kernel does it on its own
as a result of `udevd` call.
As part of the fix, `RereadPartitionTable()` calls were removed (they
trigger `BLKRRPART` and they're not needed as Talos updates partition
table on its own).
Some cleanups to make sure blockdevice is open/closed just in matching
pairs (no lingering open blockdevice instances). This is import for
`WithExclusiveLock()` calls, as it would lead to a deadlock if previous
blockdevice instance is not closed.

This refactoring is required to simplify the work to be done to support
disk encryption.
Tried to minimize amount of queries done by `blockdevice` `probe`
methods.
Instead, where we have `runtime.Runtime` we get all required blockdevices
there from blockdevice cache stored in `State().Machine().Disk()`.
This opens a way to store encryption settings in the `Partition`
objects.

This brings in `os-runtime` package and exposes resources with first
iteration of read-only API.
Two Talos resources (and one controller) are implemented:
* legacy.Service resource tracks Talos 'service' `RUNNING` state
* config.V1Alpha1 stores current runtime config
Glue point between existing runtime and new os-runtime based runtime is
in `v1alpha2` implementation and `V1Alpha2()` sub-interfaces of existing
`Runtime`, `State`, `Controller` interfaces.

This the first iteration of Wireguard network support.
What was done:
- kernel was updated to enable Wireguard kernel module.
- changed networkd to support creating Wireguard device type.
- used wgctrl to configure wireguard.
- updated `talosctl cluster create` to support generating Wireguard
network configuration automatically by just specifying the network cidr.
- added docs about Wireguard support/how to use it.

Default manifests created by bootkube so far were only enabling
pod-checkpointer for kube-apiserver. This seems to have issues with

If the node time is out of sync, it can generate incorrect
configuration. And maintenance mode does not allow us starting ntp,
because there is no containerd.
By providing current UTC time of the machine where talosctl client is
running, it is possible to force GenerateConfiguration use correct time.

Default image versions are kept as commented out examples.
This allows better experience for generating config on amd64 for arm64
servers. (e.g. for RPi).
Without embedded values in the config, Talos is going to use the
defaults which work better.

of modifying the installation in specific ways for a given SBC. This also adds support for the

This is initial commit of the installer.
What's done:
- verifying node availability before starting any operations.
- gathering information about disks on the machine.
- allows setting: install disk, hostname, machine type, installer image,
kubernetes version, dns domain, cluster-name.
- dumps/merges talosconfig to a file after applying configuration.

This builds a bundle with CNI plugins for talosctl which is
automatically downloaded by `talosctl` if CNI plugins are missing.
CNI directories are moved by default to the `~/.talos/cni` path.

Kubeconfig merge was completely rewritten to be "smarter":
* automatically apply renames done at previous stages to avoid asking

* skip checks if parts of the config match exactly
* allow overwrite as an option
* flexible way to control the output
* activating context in the end
* custom merged context name
