Fix issue of ExitCode and PID not show up in Task.Status.ContainerStatus

Browse source 
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 confusion 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.
