Specity a Google Analytics Tracking ID in the `app-config.yaml` to
enable Google Analytics tracking.
```
app:
title:
baseUrl:
googleAnalyticsTrackingId: UA-000000-0
```
If the `googleAnalyticsTrackingId` is not supplied, no tracking script
is added to the application and no tracking can occur.
Includes Helm chart changes to allow overriding the GA Tracking ID.
