[API Pull] Add Track Events to the Auth API responses

[jorgemd24]

Changes proposed in this Pull Request:

Part of #2146 .

Currently, we have two tracking events, gla_disable_product_sync_click and gla_enable_product_sync_click. However, it would also be useful to track the status of the Auth flow and when merchants revoke access.

This PR adds the following server-side event tracking:

• revoke_wpcom_api_authorization -> When the token is revoked, this event will include the status, blog id, and any error if it exists.
• update_wpcom_api_authorization -> When the Auth flow is completed, this event will include the status, blog id, and any error if it exists.

Screenshots:

Detailed test instructions:

1. Confirm tracking is allowed in WooCommerce > Settings > Advanced > Woo.com
2. To view the tracking, go to Tracks -> History (live tracking doesn't show the properties). Filter by your username and the following events: wcadmin_gla_update_wpcom_api_authorization and wcadmin_gla_revoke_wpcom_api_auth. It may take some time for the data to appear.
3. Alternatively you can use the following filter to see the events in the error log:

add_filter(
    'pre_http_request',
    function ( $pre, $args, $url ) {
        if ( str_starts_with( $url, 'https://pixel.wp.com' ) ) {
            wp_parse_str( wp_parse_url( $url, PHP_URL_QUERY ), $query_vars );
            error_log( json_encode( $query_vars, JSON_PRETTY_PRINT ) );
        }
        return $pre;
    },
    10,
    3
);

4. Enable the notification service: add_filter( 'woocommerce_gla_notifications_enabled','__return_true' );
5. Go to GLA -> Settings -> Get Early Access -> follow the steps.
6. Revoke the access by clicking in : Disable product data fetch:

Additional details:

• I included the blog_id because I thought it might help with debugging issues, but I can't see it in Tracks. I'm not sure why that is.

I included the blog_id because I thought it might help with debugging issues, but I can't see it in Tracks. I'm not sure why that is.

@jorgemd24 I yes get the blog ID (in the logs using the snippets. In tracks I didn0't check)

[jorgemd24]

Thanks @puntope for the review!

I yes get the blog ID (in the logs using the snippets. In tracks I didn0't check)

Yes, the blog_id is being sent to Tracks, and it shows in the logs, but I can't see it in Tracks. I'll need to investigate further to see if there are any restrictions on sending this parameter to Tracks.

Can you take another look to this PR?
