discover: Handle and track plugin_options
Track plugin_options in the device_handler. Plugins can be added with device_handler_add_plugin_option() and accessed via device_handler_get_plugin(). Extend discover_server to support the new 'add' and 'remove' pb-protocol actions and advertise new plugins to connecting clients. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
