In current implementation, MemberList API is served directly from server's local member structure, which could include stale information.

Serving MemberList with linearzable guarantee has the benefit of:

  1. simplify the logic in etcdctl member add (etcdctl member add sometimes fails with 3.3.15 #11186).
  2. make the process of adding a new member more robust (Start server fails with "error validating peerURLs" (race?) #10626).
