Description
Sometimes, users make poor choices when configuring their replica set. For example, they might decide to rs.add('10.3.2.1') an internal IP, then later realize that they would prefer to use a hostname rs.add('foo.example.com').
Currently this can be accomplished with an rs.add/rs.remove sequence.
It would be nice if this could be accomplished without the need for the rs.add/rs.remove (and fall out election events). This would only be possible if the user was replacing the reference with another reference to the same mongod. (I.e. if 10.3.2.1 and foo.example.com are honestly the same mongod).
