[Shunli Zhou]

When create container, there is exception in code:

The inspected docker start time using docker-py is not the required format.

The start time returned by docker cli is correct.

    Fix inspect time do not match required format

    When execute zun list, docker-py inspect may return start
    time not in required format, container.docker.driver:
    format_status_detail throw exception.

    Since we do not need the micro seconds field, trim the time
    string to [:19] and discard the microseconds field in the format
    string.
