If this binding is really optional, I'd rather move this interface into
DevToolsHttpHandler and call it RenderViewHostBinding. Clients will be able to
set it via DevToolsHttpHandler::SetRenderViewHostBinding.

Done.

If you rename the interface to RenderViewHostBinding. These will be called
GetIdentifier and ForIdentifier.

Done.
