main: Keep track of outputs created by waltham transmitter plug-in

Waltham transmitter plug-in will create the output, but we will still
require it as to set the view's output. This reads out the config file,
same as waltham transmitter, and creates an ivi_output with the output
being retrived using the transmitter_api.
