 Description   

Transitioning from removed->arbiter or from arbiter->removed->??? should error/fassert until those transitions are coded and tested (=supported).

Odd things will happen if this is allowed, like replication of data continues on an arbiter, until restarted.

We didn't fix this in Safe Reconfig since it's out of scope. I think this is still a bug.

siyuan.zhou, did we do anything for this in Safe Reconfig? Is this still something we want to do?

judah.schvimer, definitely! I linked this to Safe Reconfig.

siyuan.zhou, is this an interesting case to test/prohibit for Safe Reconfig?
