This fix tries to address the issue raised in #36139 where ExitCode and PID does not show up in Task.Status.ContainerStatus
The issue was caused by
json:",omitempty"
in PID and ExitCode which interprate 0 as null.This is confusing as ExitCode 0 does have a meaning.
This fix removes
json:",omitempty"
in ExitCode and PID, but changes ContainerStatus to pointer so that ContainerStatus does not show up at all if no content. If ContainerStatus does have a content, then ExitCode and PID will show up (even if they are 0).This fix fixes #36139.
