Tsz-wo Sze resolved RATIS-1625.
-------------------------------
Resolution: Not A Problem
We recently tested setConf with various cases in RATIS-1911. The
non-majority-add (see also RATIS-1912) case worked as expected. I believe this
is not a problem.

> As has been discussed in
> [https://lists.apache.org/thread/tt1j3jkogh71k2hvq5gtltwmphxfy736]
> , the problem is that:
> * New nodes will be stopped by the leader because it's not in the old
> configuration
> * setConfiguration won't success because it cannot communicate to new nodes,
> since they got shutdown.
> Steps to repdoduce:
> * Start a cluster with 3x nodes
> * Start 2 new nodes with 5x configuration
> * Call api to change the configuration in old nodes
> Logs when calling admin api:
