Overview: deprecate existing Talos resource API, and introduce new COSI
API.
Consequences:
* COSI API can only go via one-2-one proxy (`client.WithNode`)
* client-side API access is way easier with `state.State` wrappers
* lots of small changes on the client side to use new APIs

We add a new CRD, `serviceaccounts.talos.dev` (with `tsa` as short name), and its controller which allows users to get a `Secret` containing a short-lived Talosconfig in their namespaces with the roles they need. Additionally, we introduce the `talosctl inject serviceaccount` command to accept a YAML file with Kubernetes manifests and inject them with Talos service accounts so that they can be directly applied to Kubernetes afterwards. If Talos API access feature is enabled on Talos side, the injected workloads will be able to talk to Talos API.

It turns out there's something related to boot process in BIOS mode
which leads to initramfs corruption on later `kexec`.
Booting via GRUB is always successful.
Problem with kexec was confirmed with:
* direct boot via QEMU
* QEMU boot via iPXE (bundled with QEMU)
The root cause is not known, but the only visible difference is the
placement of RAMDISK with UEFI and BIOS boots:
```
[ 0.005508] RAMDISK: [mem 0x312dd000-0x34965fff]
```
or:
```
[ 0.003821] RAMDISK: [mem 0x711aa000-0x747a7fff]
```

As now changes to kubelet configuration can be applied without a reboot,
`talosctl upgrade-k8s` can handle the kubelet upgrades as well.
The gist is simply modifying machine config and waiting for `Node`
version to be updated, rest of the code is required for reliability of
the process.
Also fixed a bug in the API while watching deleted items with
tombstones.

The structure of the controllers is really similar to addresses and
routes:
* `LinkSpec` resource describes desired link state
* `LinkConfig` controller generates `LinkSpecs` based on machine
configuration and kernel cmdline
* `LinkMerge` controller merges multiple configuration sources into a
single `LinkSpec` paying attention to the config layer priority
* `LinkSpec` controller applies the specs to the kernel state
Controller `LinkStatus` (which was implemented before) watches the
kernel state and publishes current link status.

First, if the config for some component image (e.g. `apiServer`) is empty,
Talos pushes default image which is unknown to the script, so verify
that change is not no-op, as otherwise script will hang forvever waiting
for k8s control plane config update.
Second, with bootkube bootstrap it was fine to omit explicit kubernetes
version in upgrade test, but with Talos-managed that means that after
Talos upgrade Kubernetes gets upgraded as well (as Talos config doesn't
contain K8s version, and defaults are used). This is not what we want to
test actually.

CNI was removed from build-container which works fine for
`talosctl cluster create` clusters as it installs its own CNI, but fails
for upgrade tests as they were never updated for the CNI bundle.

Upgrade is performed by updating node configuration (node by node, service
by service), watching internal resource state to get new configuration
version and verifying that pod with matching version successfully
propagated to the API server state and pod is ready.
Process is similar to the rolling update of the DaemonSet.

This is required to upgrade from Talos 0.8.x to 0.9.x. After the cluster
is fully upgraded, control plane is still self-hosted (as it was
bootstrapped with bootkube).
Tool `talosctl convert-k8s` (and library behind it) performs the upgrade
to self-hosted version.

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`.

This allows to generating current version Talos configs (by default) or
backwards compatible configuration (e.g. for Talos 0.8).
`talosctl gen config` defaults to current version, but explicit version
can be passed to the command via flags.
`talosctl cluster create` defaults to install/container image version,
but that can be overridden. This makes `talosctl cluster create` now
compatible with 0.8.1 images out of the box.
Upgrade tests use contract based on source version in the test.
When used as a library, `VersionContract` can be omitted (defaults to
current version) or passed explicitly. `VersionContract` can be
convienietly parsed from Talos version string or specified as one of the
constants.

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).

Our upgrades are safe by default - we check etcd health, take locks,
etc. But sometimes upgrades might be a way to recover broken (or
semi-broken) cluster, in that case we need upgrade to run even if the
checks are not passing. This is not a safe way to do upgrades, but it
might be a way to recover a cluster.

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).
