generate binding for the homegraph api

[proppy]

The homegraph API is now listed under the discovery directory:
https://www.googleapis.com/discovery/v1/apis/

It would be nice to have generated bindings for it so that the smarthome library (https://github.com/actions-on-google/actions-on-google-nodejs/blob/master/src/service/smarthome/smarthome.ts) can depends on it rather than handcrafting a client.

👍 @proppy thanks for the heads up, the homegraph API should be pulled in next time we generate the client.

We don't generate the client very frequently these days, if you'd like to get a head start playing with the API, checking out this repo and running npm run generate should give you something to play with.

This has been available for a few releases :)
