Description

Why is this needed:
Container may also be killed with exitcode 255 (not normal signal), conflicts with PAIRuntimeUnknownFailed(255) https://github.com/microsoft/pai/blob/4417236c9f8b885038e7118676622fe6ea243cb1/src/k8s-job-exit-spec/config/k8s-job-exit-spec.yaml#L1197-L1198
To better avoid conflicts, check if originalUserExitCode appeared in diagnosic
if yes, current behaiour,
otherwise, it is not returned by runtime, check if the exicode is in spec and it is NOT owned (issuer) by runtime,
if yes, return the spec entry (such as SIGKILL entry),
otherwise, return PAIRuntimeExitAbnormall(256), https://github.com/microsoft/pai/blob/4417236c9f8b885038e7118676622fe6ea243cb1/src/k8s-job-exit-spec/config/k8s-job-exit-spec.yaml#L1246-L1247
