Command implements two modes:
* `fast`: conformance suite is run at maximum speed
* `certified`: conformance suite is run in serial mode, results
are capture to produce artifacts ready for CNCF submission process

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.

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.

Same as in `talosctl cluster create`. Will apply RFC6902 json patch
during the config generation if specified.

This adds a simple API and `talosctl etcd snapshot` command to stream
snapshot of etcd from one of the control plane nodes to the local file.

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.

Not exactly matching with udevd generated `by-<id>` symlinks, but should
provide sufficient amount of property selectors to be able to pick
specific disks for any kind of disk: sd card, hdd, ssd, nvme.
