Support to specify Surface Capabilities

[yoichiro]

Currently, all requests are sent from as a device which supports Audio surface only. But, many actions support multiple surfaces and send different responses depending on the surface.

At least, I think that this tool should support a screen surface. For example, if developers can specify whether want to support a screen surface or not as like the following, we will be able to cover more test cases/conditions.

const action = new ActionsOnGoogleAva(...);
...
action.screenSurfaceSupport = true;  // Default value is false
action.start(...);

I agree this is a useful change. It does require some server-side changes to accommodate.

@Fleker Probably, we can support to the screen surface by the following code below:

    send(input: string): Promise<AssistResponse> {
        const config = new embeddedAssistantPb.AssistConfig()
        ...
        config.setAudioOutConfig(new embeddedAssistantPb.AudioOutConfig())
        ...
        // Add two lines below:
        config.setScreenOutConfig(new embeddedAssistantPb.ScreenOutConfig())
        config.getScreenOutConfig().setScreenMode(3)
        ...

If we add the lines above, the result of conv.surface.capabilities.has('actions.capability.SCREEN_OUTPUT'); is true in a fulfillment code. That is, it does not require any server-side changes, I guess.

Do you have other reasons which we need to change the server-side code?

I was thinking primarily of the other possible surface capabilities, as there's not a single array of values that you control

I have started using action-on-google-testing package for our enterprise bot. During testing, I found some issue regarding failed scenarios -: 1.sometime intent doesn't match with my utterance.

2. When I enable fulfillment for webhook, I not getting any response but when I disable the fulfillment and added static response that time it was working fine.
