Review comment:
We have multiple options when we figure out that the kernel die:
- return an error then kill the process (this pr is doing that)
- restart the kernel ?
The challenge with 1, is that we maybe need to add a new status to the
`status` grpc method. like `shutdown`. We can check this status before running
like in the `checkIpythonProcessAndRestartIfDead`
The challenge with 2 is that our execute thread will always be stuck. and we
might have no way to kill it.
