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.
