retest this please, hykins |

on the result of hykins -- http://ci.hypercontainer.io:8080/job/hyperd-auto/404/console I am afraid that this PR will affect exec output in some case. We need make it clear before merge it. |

The container logger copier expect to read EOF so that it can determine the container output stream has ended. If we do not close stdout/stderr streams, the logger copier will continue waiting for a new liner to stop reading. When container stops and closes the logger, container logs are lost forever.
