As I mentioned elsewhere passing a mojo struct like

MediaRouteProviderConfig {
 bool enable_dial_discovery; 
 bool enable_cast_discovery;
}

to pass flags from the browser to the provider would be more extensible.  It
would also allow the bindings to just pass the mojo config object directly into
the MRPM, instead of keeping flags.

Done.
