If the ssh_key file is not exist like below: ssh_key: "keys/notRealFile"

The stdout will look like this:

I added also a validation for the kickstart field, because it's the same check as ssh-key Now, it's ready for review @rujutashinde @JunqiZhang0

I changed only that word in the schema s/whitboard/whiteboard , this is the only addition I made to the last push

[shay6]

I set a wrong ssh-key path: I removed the provision stage and the validate check is working as expected I removed the validate stage and run the job only with provision stage, and also the provision sends error as expected
