Management shell kills container too early

[TheJJ]

The management shell via ssh kills the container as soon as the ssh connection dies.
When restarting/powering off the VM, the ssh connection is closed before the machine is off.
-> The machine is killed before it is off.

I experienced data corruption as stuff was not yet synched to disk.

The solution is to add support in falk:
Kevin asks Falk "pls tell me when the VM is dead", then falk sends the reply when the machine went down. Kevin can then continue. (The whole thing is still timeout-wrapped so if the container doesn't go down, it's killed after x seconds).

I workarounded it by sleeping 5 seconds after the ssh is disconnected. The proper solution would be do implement async def wait_for_shutdown(timeout=60) for class FalkVM in kevin/falkvm.py.
