1. The work should only be started when we spend more than 0.5s in the ViewController
2. Check if there is data in the cache
2.1 Success: Show it and start an internet request if the cache is outdated
2.1.1 Success: Show the data
2.1.2 Failed: Silently fail
2.2 Fail: Try to get data from the internet
2.2.1 Success: Show it
2.2.2 Fail: Show the error
3. Every 5 minutes start internet request check, if cache is outdated && ViewController is visible
3.1 Success: Show the data
