* Guarantee no sneaky type puts more teams in the role list
* Leader per team and initial tests
* MiMa filters
* Second iteration (not working though)
* Verbose gossip logging etc.
* Gossip to team-nodes even if there is inter-team unreachability
* More work ...
* Marking removed nodes with tombstones in Gossip
* More test coverage for Gossip.remove
* Bug failing other multi-node tests squashed
* Multi-node test for team-split
* Review fixes - only prune tombstones on leader ticks
* Clean code is happy code.
* All I want is for MiMa to be my friend
* These constants are internal
* Making the formatting gods happy
* I used the wrong reachability for ignoring gossip :/
* Still hadn't quite gotten how reachability was supposed to work
* Review feedback applied
* Cross-team downing should still work
* Actually prune tombstones in the prune tombstones method ...
* Another round against reachability. Reachability leading with 15 - 2 so far.
