Due to the race, main goroutine might consume all the errors from
`errCh` and close `nodesCh`, so node goroutine might hit panic on send
to closed channel.
```

This PR will introduce a `-p/--exposed-ports` flag to talosctl. This
flag will allow us to enable port forwards on worker nodes only. This
will allow for ingresses on docker clusters so we can hopefully use
ingress for Arges initial bootstrapping. I modeled this after how KIND allows ingresses
[here](https://kind.sigs.k8s.io/docs/user/ingress/)

This implements `osctl cluster destroy` for Firecracker, adds
new utility command `osctl cluser show`.
Firecracker mode now has control process for firecracker VMs, allowing
clean reboots and background operations.
Lots of small fixes to Firecracker mode, clean CNI shutdown, cleaning up
netns, etc.

We have been using two packages that define a config type and a machine
type, when really they are one and the same. This unifies the types down
to one set.

This PR will allow users to issue `osctl config generate`, tweak the
configs to their liking, then use those configs to call `osctl cluster
create`.
Example workflow:
```
osctl config generate my-cluster https://10.5.0.2:6443 -o ./my-cluster
** tweaky tweak **
osctl cluster create --name my-cluster --input-dir "$PWD/my-cluster"
```

This extracts Docker Talos cluster provisioner as common code
which might be shared between `osctl cluster` and integration-test.
There should be almost no functional changes.
As proof of concept, abstract cluster readiness checks were implemented
based on provisioned cluster state. It implements same checks as
`basic-integration.sh` in pure Go via Talos/K8s clients.
`conditions` package was promoted from machined-internal to
`internal/pkg` as it is used to run the checks.
