UISP Migration to uisp.berlin.freifunk.net

[Noki]

With the rollout of babel routing and bgpdisco we changed the host suffix from .olsr to .ff. Due to the change devices can no longer reach the host and need to be migrated to another host. In order to make the uisp host a stable endpoint we should migrate it to uisp.berlin.freifunk.net.

• Add dns entries to resolte uisp.berlin.freifunk.net to the correct IP addresses (@nicolasberens)
  • Use IPv4 & IPv6 addresses reachable from the Internet so we can have a proper SSL certificate
• Setup migration in UISP to the new host (@Noki)
• Add a static hostname entry for uisp.olsr so devices can reconnect and the migration can take place (@Noki)
