Lei Jitang 6dce6bba77 Enable inspect exec if container is pause/restarting/non-running ...

if docker exec exit and at the same the the container is pause,
there could be a chance the `docker exec exit` will fail
```
$ docker exec -ti 388c7f47a06c sh
/ # exit
Error response from daemon: Container 388c7f47a06cce0856266ffd56a2ce2901689ca7a6b9cd741b37652418448f2b is paused, unpause the container before exec
```
To reproduce this error easilly, we can add a sleep in `containerPause`
```
