Steps to Reproduce

1. Execute gNOI COLD reboot without a message:

root@sonic:/# gnoi_client -notls -insecure -module System -rpc Reboot -jsonin '{"method":1}'
System Reboot
root@sonic:/# gnoi_client -notls -insecure -module System -rpc RebootStatus
System RebootStatus
{"count":1,"method":1,"status":{"status":3,"message":"HostServiceDbus::Reboot: failed to call reboot host service"}}

Impact of this regression

After merging the new reboot implementation (sonic-net/sonic-gnmi#308, sonic-net/sonic-host-services#191, #20713) gNOI COLD reboot without a message fails.
Previously it was possible to execute a gNOI COLD reboot without a message.

The reason of the failure is KeyError exception thrown by reboot host service here: https://github.com/sonic-net/sonic-host-services/blob/master/host_modules/reboot.py#L188
