Add SystemUI component to watch for keyboard attachment. 

Add a new SystemUI component to watch for keyboard attachment /
detachment. If the config specifies the name of a keyboard that is
packaged with the device, then SystemUI will ask the user if they
would like to enable BT (if disabled) and then attempt to pair to the
device.
