Migrate TTN-Gateway to The Things Stack Community Edition (aka V3)

 I just migrate my TTN-gateway to the new The Things Stack Community Edition (aka V3). 

I followed the instructions I found in the thread on GitHub.

1. Create a new gateway on the things network (link)
2. Change the server url in your local_conf.json to eu1.cloud.thethings.network
3. Restart the gateway

Unfortunately the new stack does not provide a NOC api - so my script to output the gateway status to a OLED stop working. I will invest into this next.
