This PR adds the support for CoreDNS forwarding to host DNS. We try to bind on 9th address on the first element from
`serviceSubnets` and create a simple service so k8s will not attempt to rebind it.

Before this change KubePrism used hardcoded "localhost" as destination which Go could resolve to IPv6 destination and
then fail to connect to. This change forces KubePrism to connect using IPv4 and uses hardcoded "127.0.0.1" destination so
it will always use IPv4.

This commit integrates the GOMEMLIMIT environment variable into shipped K8S
manifests when resources.limits.memory is defined. It is set to 95% of the
memory limit to optimize the performance of the Go garbage collector,
mitigating the risk of OOMKills in containerized environments.
When configuring the controller-manager or scheduler custom resources in
machine config, they where accepted, but ignored.
This commit adds Resources to NewControlPlaneSchedulerController and
NewControlPlaneControllerManagerController so machine config resources

This refactors code to handle partial machine config - only multi-doc
without v1alpha1 config.
This uses improvements from
https://github.com/cosi-project/runtime/pull/300:
* where possible, use `TransformController`
* use integrated tracker to reduce boilerplate
Sometimes fix/rewrite tests where applicable.

This commit adds support for API load balancer. Quick way to enable it is during cluster creation using new `api-server-balancer-port` flag (0 by default - disabled). When enabled all API request will be routed across
cluster control plane endpoints.

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.

Refactor more config interfaces, move config accessor interfaces
to different package to break the dependency loop.
Make `.RawV1Alpha1()` method typed to avoid type assertions everywhere.
No functional changes.

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.

This bug is pretty cosmetic, but it shows up as a wrong check when
performing worker upgrade - Talos pretends it checks e.g. kube-apiserver
version which doesn't make sense for workers.
There were two bugs in the code:
* check for machine type was done against `TypeWorker`, while
`MachineType` resource is initially created as `TypeUnknown`
* the cleanup code was not implemented
As I touched the code, I updated controller and tests to use modern
conventions.

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.
