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.

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.

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.

When Talos `controlplane` node is waiting for a bootstrap, `etcd`
contents can be recovered from a snapshot created with
`talosctl etcd snapshot` on a healthy cluster.
Bootstrap process goes same way as before, but the etcd data directory
is recovered from the snapshot.
This flow enables disaster recovery for the control plane: given that
periodic backups are available, destroy control plane nodes, re-create
them with the same config, and bootstrap one node with the saved
snapshot to recover etcd state at the time of the snapshot.

This enables golangci-lint via build tags for integration tests (this
should have been done long ago!), and fixes the linting errors.
Two tests were updated to reduce flakiness:
* apply config: wait for nodes to issue "boot done" sequence event
before proceeding
* recover: kill pods even if they appear after the initial set gets
killed (potential race condition with previous test).

The problem was that some of the health checks sort the list of the
nodes in place (via `sort.Strings()`). If cluster info provider returns
original slice, it might be mutated in such a way that it gets
corrupted.
We never noticed it before CAPI clusters, as in our tests IPs are
assigned sequentially, and sort operation is a no-op.
Specifically, the problem was with the `Nodes()` function, it returns
`append(controlPlaneNodes, workerNodes...)` slice, which by definition
might share memory with `controlPlaneNodes` slice. For example,
if control plane nodes were `4, 5, 6` and worker nodes were `3`, the
returned slice will be `4, 5, 6, 3`, and it shares memory with
`controlPlaneNodes` slice (firs three items). If we apply `sort` to the
returned slice, it re-orders it as `3, 4, 5, 6`, but as it is done
in-place, the `controlPlaneNodes` slice is now `3, 4, 5`, which is
obviously wrong.
Fix that by always returning a copy of the slice from the functions
implementing `ClusterInfo` interface.

This change is only moving packages and updating import paths.
Goal: expose `internal/pkg/provision` as `pkg/provision` to enable other
projects to import Talos provisioning library.
As cluster checks are almost always required as part of provisioning
process, package `internal/pkg/cluster` was also made public as
`pkg/cluster`.
Other changes were direct dependencies discovered by `importvet` which
were updated.
Public packages (useful, general purpose packages with stable API):
* `internal/pkg/conditions` -> `pkg/conditions`
* `internal/pkg/tail` -> `pkg/tail`
Private packages (used only on provisioning library internally):
* `internal/pkg/inmemhttp` -> `pkg/provision/internal/inmemhttp`
* `internal/pkg/kernel/vmlinuz` -> `pkg/provision/internal/vmlinuz`
* `internal/pkg/cniutils` -> `pkg/provision/internal/cniutils`

Fixes#2330
CLI tests require node discovery as `--nodes` flag is enforced for most
of the `talosctl commands`.
For clusters created via `talosctl cluster create`, cluster provisioner
state provides all the necessary information, but clusters created via
CAPI don't have the state attached.
API tests rely on Talos and Kubernetes APIs to fetch kubeconfig and
access Nodes K8s API.
CLI tests should rely only on CLI tools, so we use `kubectl get nodes` +
`talosctl kubeconfig` to fetch list of master and worker nodes.
This discovery method relies on "bootstrap" node being set in
`talosconfig` (to fetch `kubeconfig`).
