5dbc26c7a3 feat: rename osctl to talosctl
This is a rename of the osctl binary. We decided that talosctl is a
better name for the Talos CLI. This does not break any APIs, but does
make older documentation only accurate for previous versions of Talos.

33332f4c74 chore: support bootloader emulation in firecracker provisioner
Firecracker launches tries to open VM disk image before every boot,
parses partition table, finds boot partition, tries to read it as FAT32
filesystem, extracts uncompressed kernel from `bzImage` (firecracker
doesn't support `bzImage` yet), extracts initramfs and passes it to
firecracker binary.

This flow allows for extended tests, e.g. testing installer, upgrade and
downgrade tests, etc.

Bootloader emulation is disabled by default for now, can be enabled via
`--with-bootloader-emulation` flag to `osctl cluster create`.

76c2038b13 chore: implement loadbalancer for firecracker provisioner
This PR contains generic simple TCP loadbalancer code, and glue code for
firecracker provisioner to use this loadbalancer.

K8s control plane is passed through the load balancer, and Talos API is
passed only to the init node (for now, as some APIs, including
kubeconfig, don't work with non-init node).

9da687d2a3 test: firecracker provisioner fixes, implement cluster destroy
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.

2bf8540855 test: provision Talos clusters via Firecracker VMs
This is initial PR to push the initial code, it has several known
problems which are going to be addressed in follow-up PRs:

1. there's no "cluster destroy", so the only way to stop the VMs is to
`pkill firecracker`

2. provisioner creates state in `/tmp` and never deletes it, that is
required to keep cluster running when `osctl cluster create` finishes

3. doesn't run any controller process around firecracker to support
reboots/CNI cleanup (vethxyz interfaces are lingering on the host as
they're never cleaned up)

The plan is to create some structure in `~/.talos` to manage cluster
state, e.g. `~/.talos/clusters/<name>` which will contain all the
required files (disk images, file sockets, VM logs, etc.). This
directory structure will also work as a way to detect running clusters
and clean them up.

For point number 3, `osctl cluster create` is going to exec lightweight
process to control the firecracker VM process and to simulate VM reboots
if firecracker finishes cleanly (when VM reboots).
