Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions
inherit the environment from the primary process, so if the container was created with tty=false,
that means the exec session's TERM variable will default to "dumb". Users can override this by
setting TERM=xterm (or whatever is appropriate) to get the correct "smart" terminal behavior.

Remove unnecessary calls to api.GetReference
These calls are unnecessary, can be removed. `Eventf` and others just call `GetReference` on the object they are passed.

Use the generic runtime method to get the netns path. Also
move reading the container IP address into cni (based off kubenet)
instead of having it in the Docker manager code. Both old and new
methods use nsenter and /sbin/ip and should be functionally
equivalent.
