[PATCH 1/4] discover: Deprecate 'conf' user event

[Samuel Mendoza-Jonas]

The 'conf' user event is functionally very similar to the 'url' event,
in that both events result in downloading a specified configuration file
and passing it to iterate_parsers().
The 'url' event additionally allows downloading files from a directory
path and is also accessed by the UI via pb-protocol, so remove the
'conf' event and associated functions in favour of 'url' and
device_handler_process_url().
