Confusing error message on interactive run

[hongbin]

If I run a container with an incorrect command in interactive mode, it showed a confusing error message "ERROR: Invalid websocket link when attach ...". This error message is sub-optimal because the root cause of the failure is the container entered an error state (because users specify an incorrect command).

$ zun run -i cirros not-a-command
....
Waiting for container start
Waiting for container start
ERROR: Invalid websocket link when attach container:c581f573-3c17-469f-ab0c-10f6f59812eb

We need to fix it by checking the state of the container and failed it with a correct message if the container entered an error state.
