This fetches the Google Advertising ID, salts it and then applies hashing before sending a ping with it, at startup. Hashing and salting are used in order to prevent ourselves to correlate advertising IDs from the same user running different products we own off a single device. We will never send the client_id and the Google Advertising ID in the same ping.
