Natives: traffic analytics

Since we are moving more and more in to the in-person world, collecting traffic analytics data from native apps would become more and more important.

With this Epic, let's try to do it, but let's not separate the data in the Admin Panel yet. All we need to do is to start collecting the data from the native apps and show it as a summary with web app traffic analytics.

We need to do it for:

1. Streams
2. Sponsors

? Question remains whether we should do it for sessions.
