GetAttachSockets takes the name or ID of an existing container. It returns file paths for two sockets needed
to properly communicate with a container. The first is the actual I/O socket that the container uses. The
second is a "control" socket where things like resizing the TTY events are sent. If the container cannot be
found, a [ContainerNotFound](#ContainerNotFound) error will be returned.
