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).
