[WIP] one leader per cluster team (#23239)

Browse source 
* 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.
