demonstrate linux command as ophyd Device #98

A user asks how to launch a Linux command from bluesky (a command that takes some time before it finishes) and waits for it to finish, then return anything it has printed to the console.

BTW: The action cannot block execution of the bluesky RunEngine while waiting for the linux command to finish.
