Symptom
Reload/Shutdown cli's offer a force option which performs the operation without first checking and getting an ack from processes which might be using the HW. This is an ungraceful operation and should not be used by customers.
Conditions
Force reloading the HW while some traffic is flowing/HW is in use can lead to unintended consequences and some errors might be seen on the system
Workaround
Do not use the force option unless its a last resort. This change introduces a warning message informing users of the same. This will only be introduced in the 7.5.4, 7.8.1 and 7.9.1 + releases

Attention! You have chosen to force reload this node.
This is an ungraceful operation and should only be used as a last resort.
Proceed with reload? [confirm] n
Further Problem Description
Processes like npu_drvr/obflmgr will be actively using the HW while the command is issued. This can cause those processes to crash or raise a Fault on the HW which will cause additional reloads.
