The tobiko image uses sudo command that requires a CAP_AUDIT_WRITE capabilities in order to be able to write to kernel audit log. If the capability is missing we get the following error msg:
    
"sudo: unable to send audit message: Operation not permitted"
    
The message has no influence on successful execution of the tests but can be confusing for the users of the test-operator.

DoD:

• We do not see "unable to send audit message" error in the tobiko logs
