Description of problem: Having backslash in the supplied SSH public key, leaves ignition with an invalid JSON: "passwd": { "users": [ { "name": "core", "passwordHash": "!", "sshAuthorizedKeys": [ "ssh-rsa ... gmx\024358758@ALEX-P50"], "groups": [ "sudo" ]} ] }, How reproducible: 100% Actual results: Host cannot proceed to discovery. RHCOS tries to load the ignition and fails to continue. Expected results: We should escape any public SSH key, or deny it from being accepted on UI+API.
