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. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
