unknown: The kernel status is unknown, often because the connection
is disconnected or connecting. This state is determined by the kernel
connection status.
autorestarting: The kernel is restarting, initiated by the server.
This state is set by the services library, not explicitly sent from the
kernel.
starting: The kernel is starting
idle: The kernel has finished processing messages.
busy: The kernel is currently processing messages.
restarting: The kernel is restarting. This state is sent by the
Jupyter server.
dead: The kernel is dead and will not be restarted. This state is set
by the Jupyter server and is a final state.
