Sometimes `talosctl etcd snapshot` might not be available, for example
when etcd is not healthy. In that case it's possible to copy raw etcd
data directory with `talosctl cp /var/lib/etcd .` and use
`member/snap/db` to recover the cluster. But such copy won't pass
integrity checks, so they should be disabled explicitly.

For config patching, it's beneficial to have some fields to be present
in the config, even with the default (empty) value. At the same time not
all fields should be present in all versions of the config, e.g. some
config value don't apply to worker node configuration.
Empty value and nil value are treated equal by `yaml` library, but Talos
encoder can be made more smart to still output empty (non-nil) value to
the config, while skipping completely nil fields.
This PR implements that via new `talos:"omitonlyifnil"` tag and plus
moves docs for such fields into comments under the value.
GC'ed pod checkpointer config, so it doesn't get generated even as
comments (it was empty by default even for 0.8, so this just removes
comments about it).

Inline manifests work exactly same way as extra manifests, but the
manifest itself can be stored in the config body.
Example config patch:
```
--config-patch '[{"op": "replace", "path": "/cluster/inlineManifests", "value": [{"name": "foo", "contents": "apiVersion: v1\nkind: Namespace\nmetadata:\n name: ci\n"}]}]'
```

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 is mostly refactoring to adapt to the new APIs.
There are some small changes which are not user-visible immediately (but
visible when using `talosctl get` to inspect low-level details):
* `extras` namespace is removed, it was a hack to distinguish extra and
system manifests
* `Manifests` are managed by two controllers as shared outputs, stored
in the `controlplane` namespace now
* `talosctl inspect dependencies` output got slightly changed
* resources now have `md.owner` set to the controller name which manages
the resource

Instead of doing simple `--no-comments` flag, decided to use more
granular approach which allows to either disable examples, or docstring,
or both.
Thus the command looks like this:
```bash
talosctl gen config --with-docs=false --with-examples=false <...>
```
Both are enabled by default to provide better UX for users learning
Talos.

This is a complete rewrite of time sync process.
Now the time sync process starts early at boot time, and it adapts to
configuration changes:
* before config is available, `pool.ntp.org` is used
* once config is available, configured time servers are used
Controller updates same time sync resource as other controllers had
dependency on, so they have a chance to wait for the time sync event.
Talos services which depend on time now wait on same resource instead of
waiting on timed health.
New features:
* time sync now sticks to the particular time server unless there's an
error from that server, and server is changed in that case, this
improves time sync accuracy
* time sync acts on config changes immediately, so it's possible to
reconfigure time sync at any time
* there's a new 'epoch' field in time sync resources which allows
time-dependent controllers to regenerate certs when there's a big enough
jump in time
Features to implement later:
* apid shouldn't depend on timed, it should be started early and it
should regenerate certs on time jump
* trustd should be updated in same way
