Talos now supports new type of encryption keys which rely on Sealing/Unsealing randomly generated bytes with a KMS server:
```
systemDiskEncryption:
ephemeral:
keys:
- kms:
endpoint: https://1.2.3.4:443
slot: 0
```
gRPC API definitions and a simple reference implementation of the KMS server can be found in this
[repository](https://github.com/siderolabs/kms-client/blob/main/cmd/kms-server/main.go).

The controlplane label is simply injected into existing controller-based
node label flow.
For controlplane taint default NoScheduleTaint, additional controller &
resource was implemented to handle node taints.
This also fixes a problem with `allowSchedulingOnControlPlanes` not
being reactive to config changes - now it is.

This PR adds support for creating a list of API endpoints (each is pair of host and port).
It gets them from
- Machine config cluster endpoint.
- Localhost with LocalAPIServerPort if machine is control panel.
- netip.Addr[0] and port from affiliates if they are control panels.

`config.Container` implements a multi-doc container which implements
both `Container` interface (encoding, validation, etc.), and `Conifg`
interface (accessing parts of the config).
Refactor `generate` and `bundle` packages to support multi-doc, and
provide backwards compatibility.
Implement a first (mostly example) machine config document for
SideroLink API URL.
Many places don't properly support multi-doc yet (e.g. config patches).

See #7230
This is a step towards preparing for multi-doc config.
Split the `config.Provider` interface into parts which have different
implementation:
* `config.Config` accesses the config itself, it might be implemented by
`v1alpha1.Config` for example
* `config.Container` will be a set of config documents, which implement
validation, encoding, etc.
`Version()` method dropped, as it makes little sense and it was almost
not used.
`Raw()` method renamed to `RawV1Alpha1()` to support legacy direct
access to `v1alpha1.Config`, next PR will refactor more to make it
return proper type.
There will be many more changes coming up.

Fixes#7159
The change looks big, but it's actually pretty simple inside: the static
pods had an annotation which tracks a version of the secrets which
forced control plane pods to reload on a change. At the same time
`kube-apiserver` can reload certificate inputs automatically from files
without restart.
So the inputs were split: the dynamic (for kube-apiserver) inputs don't
need to be reloaded, so its version is not tracked in static pod
annotation, so they don't cause a reload. The previous non-dynamic
resource still causes a reload, but it doesn't get updated when e.g.
node addresses change.
There might be many more refactoring done, the resource chain is a bit
of a mess there, but I wanted to keep number of changes minimal to keep
this backportable.

We add the `nodeLabels` key to the machine config to allow users to add
node labels to the kubernetes Node object. A controller
reads the nodeLabels from the machine config and applies them via the
kubernetes API.
Older versions of talosctl will throw an unknown keys error if `edit mc`
is called on a node with this change.

Don't allow worker nodes to act as apid routers:
* don't try to issue client certificate for apid on worker nodes
* if worker nodes receives incoming connections with `--nodes` set to
one of the local addresses of the nodd, it routes the request to
itself without proxying
Second point allows using `talosctl -e worker -n worker` to connect
directly to the worker if the connection from the control plane is not
available for some reason.

Fixes#6119
With new stable default hostname feature, any default hostname is
disabled until the machine config is available.
Talos enters maintenance mode when the default config source is empty,
so it doesn't have any machine config available at the moment
maintenance service is started.
Hostname might be set via different sources, e.g. kernel args or via
DHCP before the machine config is available, but if all these sources
are not available, hostname won't be set at all.
This stops waiting for the hostname, and skips setting any DNS names in
the maintenance mode certificate SANs if the hostname is not available.
Also adds a regression test via new `--disable-dhcp-hostname` flag to
`talosctl cluster create`.

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.

Fix `Talos` sequencer to run only a single sequence at the same time.
Sequences priority was updated. To match the table:
| what is running (columns) what is requested (rows) | boot | reboot | reset | upgrade |
|----------------------------------------------------|------|--------|-------|---------|
| reboot | Y | Y | Y | N |
| reset | Y | N | N | N |
| upgrade | Y | N | N | N |
With a small addition that `WithTakeover` is still there.
If set, priority is ignored.
This is mainly used for `Shutdown` sequence invokation.
And if doing apply config with reboot enabled.

There should be no functional change with this PR.
The primary driver is supporting strategic merge configuration patches.
For such type of patches machine config should be loaded from incomplete
fragments, so it becomes critically important to distinguish between a
field having zero value vs. field being set in YAML.
E.g. with following struct:
```go
struct { AEnabled *bool `yaml:"a"` }
```
It's possible to distinguish between:
```yaml
a: false
```
and no metion of `a` in YAML.
Merging process trewats zero values as "not set" (skips them when
merging), so it's important to allow overriding value to explicit
`false`.

The new mode allows changing the config for a period of time, which
allows trying the configuration and automatically rolling it back in case
if it doesn't work for example.
The mode can only be used with changes that can be applied without a
reboot.
When changed it doesn't write the configuration to disk, only changes it
in memory.
`--timeout` parameter can be used to customize the rollback delay.
The default timeout is 1 minute.
Any consequent configuration change will abort try mode and the last
applied configuration will be used.

Some failures can be fixed by updating the machine configuration.
Now `userDisks` and `userFiles` do not make Talos to enter into reboot
loop but pause for 35 minutes.
Additionally, `apid` and `machined` are now started right after
containerd is up and running.
That makes it possible for the operator to connect to the node using
talosctl and fix the config.
