 Description   

Currently only the latest configuration is persisted on each member (to local.system.replset). It would be very useful to record each configuration change individually for future comparison.

With a history of config docs tools could then be written to find events, like when a host is added or removed, or a what "majority" write concern meant at a given time, or to present a history.
