Make kill, pause, and unpause parallel.

Operations like kill, pause, and unpause -- which can operation on one or
more containers -- can greatly benefit from parallizing its main job (eq kill).

In the case of pauseand unpause, an --all option as was added. pause --all will
pause all **running** containers.  And unpause --all will unpause all **paused**
containers.
