added the (untested) ability to force a recovery to the remote datacenter, even if that results in data loss. If the DR lag is more than 1 week there could be potential data corruption if any primary storage servers are still alive.

the first location in a satellite team is the one that will serve peek requests. Make sure we probably balance peek traffic by having the first servers on each team be used an equal amount of times

The master will tell the cluster controller if it is going to take a long time to recruit new logs in its DC; the cluster controller can determine if the other DC would be better and recruit there.
...
The cluster controller will not switch to the other data center if remote logs are too far behind.
We will not recruit in DCs with negative priority.
